Magnetic field due to current-carrying coil When a current flows in a wire, it creates a circular magnetic field around the wire. This magnetic field can deflect the needle of a magnetic compass.

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 ...
