The electric circuit and magnetic circuit have symmetry For

The electric circuit and magnetic circuit have symmetry. For example, the electric field intensity E is analogous to the magnetic field intensity H. We know the electric current, which is continuous in the electric wire, what is its corresponding physical quantity in the magnetic circuit? Magnetomotive force Magnetic flux Magnetic flux density Inductance

Solution

B) magnetic flux.because the area around a magnet within which magnetic force is exerted is called magnetic field.it is produced by moving electric charges.the presence and strength of a magnetic field is denoted by magnetic flux lines.and also direction of magnetic field indicated by these lines,hence magnetic flux is analogus to electric current.
