Magnetic field due to currentHard
Question
Two identical bar magnets are fixed with their centres at a distance d apart. A stationary charge Q is placed at P in between the gap of the two magnets at a distance D from the centre O a shown in the figure
The force on the charge Q is
The force on the charge Q is
Options
A.zero
B.directed along OP
C.directed along PO
D.directed perpendicular to the plane of paper
Solution
Magnetic field due to bar magnets exerts force on moving charges ly. Since the charge is at rest, zero force acts on it.
