Question

The rate of variation of potential energy for any
magnetic dipole in a uniform magnetic field varies
with angular position as​

Answer 1

Answer:

P.E=−pEcosθ=−p⋅E. This is negative when θ is acute and positive when θ is obtuse. You should verify that the product of p and E does have the dimensions of

Answer 2

Answer:

Explanation:

consider a dipole with charges +q and -q placed in a uniform electric field as shown in figure. In uniform position where potential Energy is considered as zero, we select θo as π/2r electric field, dipole experiences a torque τ
