To learn about mutual inductance from an example of a long solenoid with two windings. To illustrate the calculation of mutual inductance it is helpful to consider the specific example of two solenoids that are wound on a common cylinder. We will take the cylinder to have radius p and length L. Assume that the solenoid is much longer than its radius, so that its field can be determined from Ampère's law throughout its entire length: § B(7) - dỉ = µ-encl (Figure 1) We will consider the field that arises from solenoid 1, which has n₁ turns per unit length. The magnetic field due to solenoid 1 passes (entirely, in this case) through solenoid 2, which has №₂ turns (total turns not turns per length). Any change in magnetic flux from the field generated by solenoid 1 induces an EMF in solenoid 2 through Faraday's law of induction, E() dl=м(t).

Please answer with complete solutions. Thankyou!
A circular loop of wire lies in a plane perpendicular to a magnetic field. The magnetic field has a magnitude of 1.3 T and points out of the page as shown in the figure. The radius of the loop is 18 cm and it has a resistance of 3.2 Ω. Find the induced emf in the loop of wire if the magnetic field doubles in magnitude in 1 seconds. What is the induced current in the loop? In which direction is the induced current?
