Question
Suppose we have an even distributed magnetic field, shown as Figure.1, the black arrows give you Loop 1 the direction of magnetic field and the white arrows give you the direction of surface. 1. Which Loop has the largest magnetic field? Why? 2. If move Loop 1 to the right, is there any induced voltage generated? Why? (Assume magnetic field is even distributed everyone on the plane of this paper) 3. Propose three ways to create an induced voltage in loop 1. You are allowed to change any parameter shown in Figure 1.Explanation / Answer
Because that has large area to cover magnetic field in loop.
2. Yes
Because magnetic field is changing here.
Induced voltage generated by Faraday’s Law.
Faraday’s says, When a changing magnetic field is linked with a coil, an emf is induced in it. This change in magnetic field may be caused by changing the magnetic field strength by moving a magnet towards or away from the coil, or moving the coil into or out of the magnetic field as desired. Or in simple words, we can say that the magnitude of the emf induced in the circuit is proportional to the rate of change of flux.
3. 1)change the magnetic field.
2)move the loop perpendicular to magnetic field.
3) change the area of loop.
