Published: Tuesday 14 March 2006 - Updated: Tuesday 29 March 2011
To demonstrate that a current carrying conductor in a magnetic field experiences a force given by dF= I dl X B
- Rola Permanent Magnet
- AC/DC Power supply (10 Amps)
- Retort stands and attachments as shown

Force on a Current Carrying Wire in B Field
The aluminium strip is hung between the poles of the magnet with the aid of the two retort stands as shown. On closing the switch S1 the strip experiences a force due to the interaction between the current I and the magnetic field B.
The direction of current flow may be reversed via the rotary switch S2 to deflect the strip in the opposite direction.
