The area enclosed by a hysteresis loop is a measure of

Which of the following is represented by the area enclosed by a hysteresis loop (B - H curve)?

Explain hysteresis loop

A rectangular loop carrying a current i is placed in a uniform magnetic field B. The area enclosed by the loop is A. If there are n turns in the loop, the torque acting on the loop is given by

The area of hysteresis loop of a magnetic material A is larger than of another magnetic materialB. Which of the two materials is better suited for use as the core of an electromagnet?

The area of hysteresis loop of a material is equinalent to 250 joule. When 10 kg material is magnetised by an alternating field of 50 Hz then energy lost in one hour will be if the density of material is 7.5 gm//cm^(2)

Consider the following statements (i) for a permanent magnet the area of a hysteresis loop is allowed to be large (ii) Coercivity o the material in permanent magnets should be small. Which of the following statements is/are true?

Find the area enclosed by the loop of the curve y^(2) = (x-1) (x-2)^(2) .
