Strength of the force is expressed by its ____________
Explanation
Hence the strength of the force is expressed by its magnitude.
A magnetic pole of pole strength 9.2 A m. is placed in a field of induction 50x10−6 Tesla. The force experienced by the pole is :
Two poles of same strength attract each other with a force of magnitude F when placed at the corners of an equilateral triangle. If a north pole of the same strength is placed at the third vertex, it experiences a force of magnitude
Strength of a force is expressed by
