1. Mognetic Flux There are three ways to change magnetic flux: change the area A change the magnitude of magnetic field B, and change the orientation of plane e. Q.1 A square coil parallel to page enters a region where a unform magnetic field is directed perpendicularly into a page, travels through the region at a constant speed, and exits. (a) From the figure below, find one which shows the magnetic fux inside the coll as a function of time. (b) the edge length of the coil is a- 20cm and the magnetic field s B-0.5T. What is the maximum flux inside the coil? 01.2 A square coil placed in a uniform magnetic field rotates around one of its edges as shown in figure below. (a) From the following plots, find one which shows the magnetic fux inside the col as a function of angle o (b) If the edge length of the coil is a- 20cm and the magnitude field is B-0:5T. What is the maximum flux inside the coil? 0Explanation / Answer
1)
a)
correct option is (d)
b)
maximum flux=B*A
=B*(a^2)
=0.5*(0.2^2)
=0.02 Wb
