What causes a change in magnetic flux?

The change could be produced by changing the magnetic field strength, moving a magnet toward or away from the coil, moving the coil into or out of the magnetic field, rotating the coil relative to the magnet, etc. It involves the interaction of charge with magnetic field.

When magnetic flux linked with conducting loop is constant then emf induced is?

when the magnetic flux linked with conducting loop is zero then emf induced is always zero.

What happens when you have a changing magnetic flux?

As seen in previous Atoms, any change in magnetic flux induces an electromotive force (EMF) opposing that change—a process known as induction. Motion is one of the major causes of induction. For example, a magnet moved toward a coil induces an EMF, and a coil moved toward a magnet produces a similar EMF.

How can magnetic flux be zero when the magnetic field is not zero?

The magnetic flux is generated when there is change in the magnitude of the magnetic field as well as its direction. If the magnetic field is parallel to the place of the area exposed then the magnetic flux generated is zero when the magnetic field is not zero.

When magnetic flux linked with conducting loop is constant and emf induced is zero?

when the emf induced in conducting loop is zero, then the magnetic flux linked with the loop must be zero.

Why is the magnetic flux zero?

Because magnetic field lines are continuous loops, all closed surfaces have as many magnetic field lines going in as coming out. Hence, the net magnetic flux through a closed surface is zero.

What happens when the magnetic flux is zero?

magnitude of 1 when , the angle between the area vector and the magnetic field, is either 0° or 180°. As shown in Figure 20.2, if the plane of the paper is parallel to the magnetic field, no field lines pass through the paper and the magnetic flux is zero.

What happens when the magnetic flux changes in a loop?

If the magnetic flux through a loop of wire changes for any reason either by changing the area, A, of the loop or the field, B, through the loop Then an EMF (voltage) will be induced in the wire. This voltage will cause a current to flow (the induced current in the loop).

What is the magnetic flux density of a magnet?

Magnetic flux density (B) is defined as the force acting per unit current per unit length on a wire placed at right angles to the magnetic field. Where, =length of wire =total force acting on the wire =current flowing through the wire.

How does a magnet interact with a moving charge?

Magnetic Field. Interaction of magnetic force and charge – The moving charge interacts with the fixed magnet. The force between them is at a maximum when the velocity of the charge is perpendicular to the magnetic field.

What happens when a coil of wire moves through a magnetic field?

When a coil of wire is moved through a magnetic field a voltage is generated which depends on the magnetic flux through the area of the coil. This is described by Faraday’s law and is explored in our article on Faraday’s law.
