A coil of wire, or solenoid, consists of a wire coiled up into a spiral shape. When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet.

The magnetic field around a current carrying conductor can be depicted ... and a magnetic compass is placed over the conducting wire, the needle of the compass deflects in the direction of west.

I had cause to demonstrate the magnetic field around a wire, and ended up with an 8A current in a vertical wire, battling with the Earth’s magnetic field. My borrowed idea was to put a ring of eight ...

As with all currents, the induced current creates a magnetic field around itself ... force on the conductor carrying the current In which direction will this wire feel a force?

Attach power supply leads to wire. Do not turn on for longer than necessary since the current carrying conductor becomes hot over ... Place compasses at various locations in and around the solenoid.

When an electric current passes through a metal wire, a magnetic field forms around that wire (see diagram at right). Likewise, a wire passing through a magnetic field creates an electric current ...

The magnetic field around a straight wire is circular and follows the right-hand rule. When an electric current flows through the wire, it generates a magnetic field concentrically surrounding the ...

Here is an example where I put a current carrying wire right over the compass needle. Since the compass is underneath the wire, the magnetic field due to the wire will be 90° to the Earth's ...

When exposed to a strong magnetic field, some superconductors will ... Unless, that is, you can make your current-carrying wire go from a normal conductor to a superconductor.
