What is the Ampere Swimming Rule?

Answer : If a swimmer swims in the current direction while facing a magnetic needle, the north pole of the magnetic field deflects towards his left hand and the south pole towards his right hand, according to Ampere’s swimming rule.

The word ‘SNOW’ can also help remember this guideline. It indicates that if the current flows from south to north, the North Pole will be deflected to the east.

Around a permanent magnet, a continuous electric current flows in one direction. The magnetic field is stationary and referred to as a magnetostatics field. At each given time, its magnitude and trajectory remain consistent.
