the expression for the potential energy of acurrent loop when it is placed in amagnetic field

Asked by anithaguthula666 | 29 Mar, 2019, 09:43: PM

Expert Answer

Just like an electric dipole

The potential energy of the loop in an external magnetic field is

U = -μ.B ( scalar product of magnetic moment and magnetic field)

U = -μB cosθ where θ is the angle between magnetic moment and magnetic field.

Magnetic moment μ is define as

μ = IA

I is THE CURRENT an A is the area of the loop

in this quesn correct answer are give 1,2,3. but in 2,3 magnetic field is a vector quantity. so to make it same at 2 points we need direction and magnitude to be same. But in case of straight wire magnitude can be same at a radius but the direction cant be same. So how 2 and 3 are correct AND 4 should be correct because in formula B is inversely prop to r are the answers given wrong ?

I have one more doubt in the previous question I asked. Doubt: In the figure, what will be the net magnetic field between the wires on the point of intersection. (I think the direction of the magnetic fields due to the two wires won't be opposite on the point of intersection between the wires so, the net magnetic field should not be zero there..)

What is the magnitude and direction of the magnetic field due to straight current carrying wire on that wire? In the uploaded image, two wires are at right angles in a plane carry equal currents. At what points in the plane is the magnetic field zero?
