Frequently Asked Questions

What is the force on a magnetic dipole?

Force between magnets. The most elementary force between magnets, therefore, is the magnetic dipole - dipole interaction. If all of the magnetic dipoles that make up two magnets are known then the net force on both magnets can be determined by summing up all these interactions between the dipoles of the first magnet and that of the second.

Why is Earth like a magnetic dipole?

Earth has a magnetic field. Therefore there must be a lot of iron in the core of the Earth. That may seem ridiculously basic but it's simple deduction. Not only does the Earth have a magnetic field but it also has an electric charge, known as a dipole moment.

How to find magnetic dipole moment?

Derivation of Magnetic Dipole Moment Formula. Magnetic Dipole moment- The magnetic field, B due to a current loop carrying a current i of radius, R at a distance l along its axis is given by: B = \( \frac {μ_0 i R^2}{2(R^2~+~l^2 )^{\frac32}}\)

What is a dipole magnet?

A dipole magnet is a magnet in which opposite poles (i.e., North and South poles) are on opposite sides of the magnet.
