Their connection with each other is established as a result of Faraday's law of induction. This law states that a change in the magnetic field can produce electricity. This is due to the production of an electromotive force from the loop which results in the generation of electricity.

Why is there a cosθ in the formula of magnetic flux?

Aadit Singh Uppal

This is because the original formula of magnetic flux is a dot product. As a result, the cos? in the formula appears when we remove the dot product of the formula. This cos? signifies that the direction of magnetic flux should always be perpendicular if its value is zero.

What is the difference between magnetic flux and magnetic flux density?

Aadit Singh Uppal

The key difference between both these terms is that magnetic flux density is the magnetic field in a particular unit area. Whereas, magnetic flux is the quantity of magnetic field in a particular space. Magnetic flux is a scalar quantity whereas magnetic flux density is a vector quantity.
