Electromagnetism Right hand rule

Question 1

What is the right hand rule?

Answer 1

The right hand grip rule
It is often useful to be able to remember which way the field points (the direction a compass needle will point) when placed near the wire. The easiest way to do this is called the ‘right hand grip rule’.

Hold out your right hand with your fingers tucked in and your thumb pointing upwards:

the thumb is equal to the direction of current
the fingers are equal to the magnetic field direction
