Equipment: A compass, iron filings, a current carrying conductor and a 40 Amp power supply. What it does: The compass shows the direction of the field lines around the conductor. The iron filings line ...

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.

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 ...

Safety note: the wire can ... up' and the magnetic field lines flow in an anticlockwise direction. In this picture, the battery terminals have been swapped around so the current is flowing down ...

Figure 1 shows a simple air-cored winding. A current-carrying conductor creates its own magnetic field (B), which produces flux lines around the conductor. In this example, 10 turns of wire carry a dc ...

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 ...
