Physics Question on Moving charges and magnetism
A current loop in a magnetic field :
A
Can be in equilibrium in two orientations, one stable while the other is unstable.
B
Experiences a torque whether the field is uniform or non uniform in all orientations
C
Can be in equilibrium in one orientation
D
Can be in equilibrium in two orientations, both the euilibrium states are unstable
Answer
Can be in equilibrium in two orientations, one stable while the other is unstable.
Explanation
Solution
θ=0∘ stable equilibrium
θ=180∘ unstable equilibrium
