Circular Coil

This apparatus offers a clear and easy way to observe magnetic fields generated by a constant electrical current. Iron filings can be scattered on the clear surface which passes through the coil and when a current then flows around the coil, the magnetic lines of force will be shown by the alignment of the filings. The apparatus can also be used in conjunction with a magnetic field sensor and/or datalogger. Requires high current laboratory power supply (8-10 A) for best effect. Weight: 1.2 kg. Dimensions (L x W x H): 300 x 200 x 250 mm.
