How does force exerted by two magnets change as the magnets are moved farther apart?
The force exerted by two magnets decreases as they are moved farther apart. This is because the strength of the magnetic field weakens with distance. The force between two magnets follows an inverse square law relationship with distance.
How do magnets work?
Magnets have magnetic fields that attract items containing iron. Some of the substances attracted to magnets include iron, nickel, and steel. To understand a magnet you must first understand the magnetic field. A magnetic field is created as the result of moving charges such as electrons. A magnet's magnetic field either attracts or repels certain metals, as well as other magnets. A magnet has two ends that are referred to as poles. One pole is called north and the other one is referred to as south. To attract magnets to each other, you have to place opposite ends of two magnets near each other. Placing like ends of two magnets near each other causes the opposite to occur; the two magnets repel each other. A magnet is any object that has a magnetic field. It attracts ferrous objects like pieces of iron, steel, nickel and cobalt. In the early days, the Greeks observed that the naturally occurring 'lodestone' attracted iron pieces. From that day onwards began the journey into the discovery of magnets. These days magnets are made artificially in various shapes and sizes depending on their use. One of the most common magnets - the bar magnet - is a long, rectangular bar of uniform cross-section that attracts pieces of ferrous objects. The magnetic compass needle is also commonly used. The compass needle is a tiny magnet which is free to move horizontally on a pivot. One end of the compass needle points in the North direction and the other end points in the South direction. The end of a freely pivoted magnet will always point in the North-South direction. The end that points in the North is called the North Pole of the magnet and the end that points South is called the South Pole of the magnet. It has been proven by experiments that like magnetic poles repel each other whereas unlike poles attract each other. What is a magnetic field? The space surrounding a magnet, in which magnetic force is exerted, is called a magnetic field. If a bar magnet is placed in such a field, it will experience magnetic forces. However, the field will continue to exist even if the magnet is removed. The direction of magnetic field at a point is the direction of the resultant force acting on a hypothetical North Pole placed at that point. When current flows in a wire, a magnetic field is created around the wire. From this it has been inferred that magnetic fields are produced by the motion of electrical charges. A magnetic field of a bar magnet thus results from the motion of negatively charged electrons in the magnet. Just as an electric field is described by drawing the electric lines of force, in the same way, a magnetic field is described by drawing the magnetic lines of force. When a small north magnetic pole is placed in the magnetic field created by a magnet, it will experience a force. And if the North Pole is free, it will move under the influence of magnetic field. The path traced by a North magnetic pole free to move under the influence of a magnetic field is called a magnetic line of force. In other words, the magnetic lines of force are the lines drawn in a magnetic field along which a north magnetic pole would move. The direction of a magnetic line of force at any point gives the direction of the magnetic force on a north pole placed at that point. Since the direction of magnetic line of force is the direction of force on a North Pole, so the magnetic lines of force always begin on the N-pole of a magnet and end on the S-pole of the magnet. A small magnetic compass when moved along a line of force always sets itself along the line tangential to it. So, a line drawn from the South Pole of the compass to its North Pole indicates the direction of the magnetic field. # The magnetic lines of force originate from the North Pole of a magnet and end at its South Pole. # The magnetic lines of force come closer to one another near the poles of a magnet but they are widely separated at other places. # The magnetic lines of force do not intersect (or cross) one another. # When a magnetic compass is placed at different points on a magnetic line of force, it aligns itself along the tangent to the line of force at that point. These are just some of the basic concepts of magnetism. One cannot possibly grasp the depth and appreciate the versatility of magnets without reading more about the uses of magnets, the Earth as a huge magnet and electromagnetism among other things.
Where does a compass point when it is moved close to a magnet?
That depends on which pole of the magnet it is moved close to. If it is brought close to the "South" pole of the magnet, the "North" pointer of the compass will be attracted to the magnet. If it is brought close to the "North" pole of the magnet, the "North" pointer of the compass will be repelled and will point AWAY from the magnet, while the "South" end of the compass pointer will point to the magnet.
How is a moving magnet used to create electricity?
makes current flow through a magnet
How can magnet produce current?
A magnetic field can induce an electric current in a conductor when there is a relative motion between the magnetic field and the conductor, according to Faraday's law of electromagnetic induction. When a conductor is moved within the magnetic field or the magnetic field moves relative to the conductor, it creates a changing magnetic flux, which generates an electromotive force (EMF) that drives a current to flow in the conductor.
Which object cannot be moved by a magnet?
Any object that is nuetral that does not have magnetic pole's
Which object cannot be moved by magnet?
Any object that is nuetral that does not have magnetic pole's
What happens when a magnet is moved towards a coil?
You will generate electricity. As the wire cuts through the magnetic field.As the magnet is moved, there will be an induced electro-motive force (EMF) which can cause a current in the coil. Once the magnet stops moving, the current will go to zero.
Why is the deflection in the galvanometer reversed when the magnet is moved in and out in a solenoid?
When the magnet is moved into the solenoid, the change in magnetic field induces an electric current in the solenoid. This induced current then creates a magnetic field that opposes the initial magnetic field created by the permanent magnet. This opposing magnetic field causes the galvanometer deflection to be reversed.
How does force exerted by two magnets change as the magnets are moved farther apart?
The force exerted by two magnets decreases as they are moved farther apart. This is because the strength of the magnetic field weakens with distance. The force between two magnets follows an inverse square law relationship with distance.
Force is applied to an object and the object is moved over a distance in the same direction of the applied force is the definition of?
Work is applied to an object and the object is moved over a distance in the same direction of the applied force.
Can you move granite with a magnet?
No, granite is not magnetic and cannot be moved with a magnet. The minerals that make up granite, such as quartz and feldspar, are not attracted to magnets.
What is the weight of the object being moved is called?
resistance force.
What is accomplished when an object is moved by force?
When an object is moved by force, work is being done on the object by transferring energy to it. This can result in the object gaining kinetic energy or changing its position. The amount of work done is equal to the force applied multiplied by the distance the object is moved.
Work is done when a force is applied to an object if the object?
is moved
What is the product of the force on an object and the distance through which the object is moved?
work
