A wire loop with radius a and resistance R is in a magnetic field as shown. The magnetic field is B = Bot and it points straight up. B 1. Find an expression for the magnetic flux through the loop in terms of the given quantities. 2. Find an expression for the emf induced in the loop in terms of the given quantities. 3. Find an expression for the magnitude of the current induced in the loop in terms of the given quantities. 4. Which way does the current in the loop flow, and why? 5. This is an example of induction. In your own words, explain at least two ways that induction is involved in generating or transporting electricity
