You obviously cannot more a magnet through a coil in the direction of the current, because the magnet must move, axially, along the length of the coil, while the current moves radially, around the coil.
However, if you move a conductor within a coil carrying a d.c. current, then the magnet will induce a voltage into that coil which will oppose the voltage applied to the coil.

What kills you when you get an electric shock?
An electric shock can stop the heart or interfere with the normal electrical signals in the body, leading to cardiac arrest. It can also cause burns or tissue damage, which can be life-threatening if severe. Additionally, the current can disrupt the normal functioning of the nervous system and vital organs, potentially resulting in death.
How does a voltage cause current to do work?
When a voltage is applied across a circuit, it creates an electric field that exerts a force on the charged particles in the circuit, causing them to move and thus creating a current. This current flowing through a load, such as a light bulb or motor, can perform work by converting electrical energy into other forms, such as light or mechanical motion.
How does electricity cause magnetism?
Changing the amount of magnetic field (known as "flux") through a conductor exerts a force on charged particles (electrons in the wire). A change in magnetic field strength in a region of space induces an electric field which circles the magnetic field lines, surprisingly whether or not there is a conductor there or not. It turns out that magnetism and electricity are inherently linked, they are kind of manifestations of the same thing. If "something" has the property of electric charge, it creates an electric field. If that something moves, it creates a magnetic field.
What happens to the bar magnet as it nears the U magnet the bar magnet will?
Move towards the U magnet so that the poles attach.
How hot can a magnet get?
It depends on the type of magnet. The Curie Point is the point above which a material cannot be a permanent magnet. For iron-type magnets, this is about 770C. Of course, not all magnets are caused by ferromagnetism. An electric current produces a magnetic field, regardless of the temperature. The earth's core approaches a temperature of 5000 C, but the Earth still has a magnetic field caused by swirling currents in the core of the earth.
How do you make electricity using only a magnet?
Electricity can be generated using a magnet in combination with a coil of wire. When the magnet moves past or through the coil, it induces an electric current in the wire due to electromagnetic induction. This phenomenon is the basis of how generators produce electricity in power plants and electric motors convert electrical energy into mechanical energy.
How does an electric generator give electricity?
By rotating a magnet inside of coils of wire. The magnetic lines of flux going through the wires cause a current to flow in the wires.
How does moving magnet generate electricity?
When a magnet moves near a conductor, such as a coil of wire, it creates a changing magnetic field. This changing magnetic field induces an electric current to flow in the wire, generating electricity through electromagnetic induction.
What is a strong short lived magnet created by a looped electrical current?
A strong short-lived magnet created by a looped electrical current is an electromagnet. When an electric current flows through a coil of wire, it induces a magnetic field around the coil, which can attract or repel magnetic materials. Turning off the current will cause the magnetic field to cease.
A horseshoe magnet is moved back and forth across a piece of copper wire an electric current is detectable in the wire?
yes, it will be very small but the inductance from the magnet should stimulate a current in the wire as it will cause electrons to move.
How does a dynamo generate electricity?
A dynamo passes a magnet past a coil. The movement of the magnet past the wire causes eddy currents to develop which cause electrons to align and move through the wire. If there is enough wire and a strong enough magnet, the current (flow of electrons) is enough to become useful and power a device. It is the growing and shrinking lines of force that cause the electrons to develop this alignment and therefore the electric current.
Can electricity cause a magnetic effect?
Yes, electricity can create a magnetic effect through the interaction of moving electric charges. When electric current flows through a conductor, it generates a magnetic field around the conductor, as described by Ampere's law. This principle is utilized in electromagnets and devices such as motors and transformers.
Does an electric current run through your body during foot detox?
Yes, during the ionic foot detoxication electric current runs through the body of the given patient. The electric current is however very low to cause harm to the body of the patient.
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.
How electricity generated in dyanamo?
A dynamo is an electric generator. The basic principle is that, when a wire (or any conductor, for that matter) moves through a magnetic field, a voltage is is induced across the wire. This will cause current to flow.
Can Magnetism cause an electric current to flow in a conductor?
Yes, a MOVING magnetic field will cause electric current to flow in a conductor. Conversely an electric current flowing in a conductor will cause a magnetic field.
How could Theresa cause an electric current to flow through one of the copper wires studyisland?
To cause an electric current to flow through one of the copper wires, Theresa would need to connect the wire to a power source, such as a battery or electrical outlet. By completing a circuit with the wire connecting the positive and negative terminals of the power source, electrons will flow through the wire, creating an electric current.
