Read the following passage and answer the questions that follow :
Bhoumik was playing with a magnetic compass near a current carrying spring-like device. He observed that the compass needle shows deflection whenever he goes close to the device. After observing it, he started running around the device. Now, he observed that the compass needle is continuously changing its direction and tries to orient itself along the North-South direction of the Earth.
(iii) (b) When a moving electron enters in a magnetic field, what will happen to its motion ? State the law required to explain your observation of moving electron in a magnetic field.
