Question

Two coils have mutual inductance M=3.25*10-4H. The current iin the first coil increases at a uniform rate of 830A/s. a.) What is the magnitude of the induced emf in the secondcoil? Is it constant? I am wondering how we know that the magnitude is constant. Ihad no problems solving the problem but am struggling with theconcept of constant magnitude. Thank you.

Explanation / Answer

induced emf= M di / dt = - 3.25 x10-4 * 830 = -0.269V as M and di/dt constant magnitude of emf constant.
