How current is produced in electromagnetic induction?

It occurs whenever a magnetic field and an electric conductor move relative to one another so the conductor crosses lines of force in the magnetic field. The current produced by electromagnetic induction is greater when the magnet or coil moves faster, the coil has more turns, or the magnet is stronger.

Can you produce current in a wire with a magnet that is sitting still?

Explain why a magnet sitting next to a wire does not induce a current in the wire. A change in the magnetic field of a coil of wire will cause a voltage to be induced in the coil. If the magnet sitting next to the wire does not move, there is no electric current in the wire.

The strength of the magnetic field increases as:

The number of turns in the coil increases. An iron core makes a strong electromagnet which can be easily magnetised and demagnetised.

Why does increasing the number of coils increase the strength of an electromagnet?

Doubling the number of coils doubles the mmf (ampere-turns): “By maintaining the same current and increasing the number of loops or turns of the coil, the strength of the magnetic field increases because each loop or turn of the coil sets up its own magnetic field.

What generates the magnetic field in a current carrying wire?

Earth’s magnetic field is generated by a feedback loop in the liquid outer core: Current loops generate magnetic fields; a changing magnetic field generates an electric field; and the electric and magnetic fields exert a force on the charges that are flowing in currents (the Lorentz force).

Why the magnetic field is stronger at the poles?

For a magnet, the flux lines repel each other so the field will be weaker at the sides. But they are concentrated at the poles, where they originate, so the field is stronger.

Why magnetic field strength is greatest at the poles?

Originally Answered: Why is a magnetic field stronger at the magnetic poles? Magnetic field is stronger at poles because magnetic field lines are very close to each other near the poles. In other words , near the poles magnetic flux density is maximum because of which magnetic field is stronger at that position.
