## What happens when you move a magnet towards a coil?

Magnet and Coil When a magnet is moved into a coil of wire, changing the magnetic field and magnetic flux through the coil, a voltage will be generated in the coil according to Faraday’s Law. The polarity of the induced emf is such that it produces a current whose magnetic field opposes the change that produces it.

## When the coil and the magnet are in the same plane the current induced in the coil will be?

Induced current will be zero.

What happened to the magnetic fields when we pushed the magnet and the coil closer together?

We figure out: The magnetic field around a magnet (and thus an electromagnet) gets stronger when it is closer to another magnet, which means that the force between two magnets will be stronger as the magnets get closer together.

What happens when you move the north side of the magnet into the coil?

When we induce a current in the coil, it becomes an electromagnet. One end of the coil is a north pole and the other end is a south pole. When the north pole of our magnet is moving towards the left hand end of the coil, the induced current flows anticlockwise (as we look at the left hand end).

### What happens when the north pole of a magnet is brought near a coil?

Because like magnetic poles repel each other, Lenz’s law states that when the north pole of the bar magnet is approaching the coil, the induced current flows in such a way as to make the side of the coil nearest the pole of the bar magnet itself a north pole to oppose the approaching bar magnet.

### What will be the effect on the coil and the magnet when we connect the coil of wire to a battery?

When the electric current moves through a wire, it makes a magnetic field. If you coil the wire around and around, it will make the magnetic force stronger, but it will still be pretty weak. There is another way that uses electricity to make a temporary magnet, called an electromagnet.

When the north pole of a magnet is brought towards the coil the galvanometer needle indicates?

When the north pole of the magnet is brought towards the coil, the galvanometer shows a sudden deflection indicating that a current is induced in the coil.

When the north pole of a bar magnet approaches the coil and then move away?

when a north pole of a bar magnet approaches towards coil then induced current is produced in which direction. The induced current is produced in the anti clockwise direction. As the north pole approaches the coil the face of the coil itself becomes the north pole.
