Where is the magnitude of the magnetic field around a permanent magnet greatest?
The magnitude of the magnetic field around a permanent magnet is greatest at the poles of the magnet. This is where the magnetic field lines are most closely packed and the field strength is the highest.
What are the types of magnets?
Ferro-magnets, permanent magnets, temporary magnets, and electromagnets. Ferro-magnets are magnets that are magnetic at a higher temperature than room temperature. do not quote me on that. permanent magnets are magnets that are always magnets, they are the kinds you use a lot. Temporary magnets are things that are magnetic in an extrenal magnetic field. Last but not least, electromagnets. Electromagnets are coils of wire around a cobalt, nickel, or iron. When ou run electricity through the wire, the core and wire become magnetic.
What shape of a permanent magnet corresponds to the magnetic field formed by a solenoid?
A solenoid typically produces a magnetic field similar to that of a bar magnet. The magnetic field lines form loops around the solenoid, making it closely resemble a bar magnet with north and south poles at either end.
What is the average magnitude of earthquakes worldwide?
The average magnitude of earthquakes worldwide is around 4.5 on the Richter scale.
What is the space all around a magnet called?
The space around a magnet where its magnetic influence can be felt is called the magnetic field. It is the region in which magnetic forces are experienced due to the presence of the magnet.
Where is the magnitude of the magnetic field around a permanent magnet greatest?
The magnitude of the magnetic field around a permanent magnet is greatest at the poles of the magnet. This is where the magnetic field lines are most closely packed and the field strength is the highest.
How is a permanentmagnet different from a electromagnet?
a permanent magnet is always magnetic as an electromagnet is only magnetic when it is wound around with wire and energised
What three features do magnetic field lines show?
Magnetic field lines show the direction of the magnetic field, the magnitude of the magnetic field (closeness of the lines), and the shape of the magnetic field around a magnet or current-carrying wire.
What is the different electromagnets and permanent magnet?
Electromagnets are non permanent magnets. They got magnetic field because of applied electric field. They lost their magnetic field which was around that, when the applied electric field is stopped. permanent magnets have magnetic property always with it. Permanent magnetic property loses when we heat the material. It cannot be regained once again. But electromagnets are capable of regaining its magnetic properties.
What is a non permanent magnet?
An electromagnet (a coil around a soft iron core) will only be magnetic when current changes in the coil and so is not permanent.
Why magnetic force around the electromagnet is not permanent?
An electromagnet is only live (magnetised) when a current is flowing through the coil.
What can decrease the magnetic field around a wire?
Decreasing the current flowing through the wire or increasing the distance from the wire are both ways to decrease the magnetic field around a wire. Adding a material that is not permeable to magnetic fields around the wire can also reduce the strength of the magnetic field.
What are three ways electromagnet and a permanent are the same?
both are magnetic, both can be used to produce an electric current if around a wire
Does Magnetic forces act when electrons move?
Yes. To be more accurate, a magnetic field is caused whenever there are moving electrical charges. Even the magnetic field in a permanent magnet are caused by more electrons moving around their atoms in one direction, than in the other.Yes.

How is magnitude of a magnetic field calculated?
To get the magnitude of a magnetic field calculation you will have to do a few steps. First you will have to integrate around the curve starting at 0 and get the radians then you can get the total sum of P.
Why can an electric current create a magnetic field?
An electric current creates a magnetic field because moving charges generate a magnetic field around them according to the right-hand rule. This magnetic field is perpendicular to both the direction of the current and the surrounding space. The strength of the magnetic field is dependent on the magnitude of the current.
What is formed around the conductor whenever an electric current flows through a conductor?
A magnetic field is formed around the conductor when an electric current flows through it. The strength of the magnetic field is directly proportional to the magnitude of the current flowing through the conductor.
