An emf of 0.45 V is induced between the ends of a metal bar moving through a magnetic field of 0.22 T. What field strength would be needed to produce an emf of 1.5 V between the ends of the bar, assuming that all other factors remain the same?
Homework Answers
as we know
e = BLv
considering all factors to be constant
e1/e2 = B1/B2
0.45/ 1.5 = 0.22 / B2
B2 = 0.73333 T

Consider a 16.5 cm long metal bar moving horizontally across a vertical magnetic field at a speed of 7.4 m/s. The magnetic field strength is 2.45 T. If the ends of the bar are connected to a 18.2 ohm resistor, find the power dissipated in the resistor while the bar is moving. Calculate the answer in watts (W) and rounded to three significant figures please. :)

A metal bar of height 20cm lying in the plane of the page is
moved through a magnetic field at a speed of 0.2m/s towards the
right (see the figure below). The field has magnitude 0.5T and
