How can a generator create current in a wire?

How can a generator create current in a wire?

The simplest generator consists of just a coil of wire and a bar magnet. When you push the magnet through the middle of the coil, an electric current is produced in the wire. The current flows in one direction as the magnet is pushed in, and in the other direction as the magnet is removed.

Who generates electricity by moving a magnet through a coil of copper wire?

Michael Faraday

What happens to the direction of the magnetic field around the copper wire loop as it turns?

The right-hand rule gives the direction of the field inside the loop of wire. The magnetic field turns back the other way outside of the loop. Thus the magnetic field pointing from north to south points in the direction of the force on a NORTH POLE of a magnet.

How does the direction of the current in the loop compare to the electric field?

How does the direction of the current in the loop compare to the electric field? Currents in wires are carried by moving electrons, which are negatively charged. Therefore, the electrons move in the opposite direction as the arrow on the wire.

What happens to the magnetic field when you switch to AC voltage?

With the AC current, it constantly (continuously) changes its current direction, hence the North and the South poles will change continuously, too. That is an application for the motor. When you change the direction of current, the curl magnetic field will just reverse the direction.

Which wire when current flows through it would be surrounded by the strongest magnetic field?

Answer: The strongest magnetic field is in (c) . When the no of turns around a wire increases, the associated electric field increase. Hence, the magnetic field will be strongest.

What difference does the thickness height of the coil wrap wire make in the effectiveness of your magnet?

The strength of the magnet will increase with the increase in the thickness of the wire too because it is already known that resistance is inversely proportional to cross-sectional area. Thus as resistance drops, more current will flow through the electromagnet causing a larger magnetic field.
