Consider a region with homogeneous magnetic field. The region has a rectangular cross-section with sides a=3.0 m, b=2.0 m and the magnetic induction vector B=1.0⋅10−3 T is perpendicular to this cross-section. We place a straight wire in parallel to the side a, such that its free ends lie outside the region with the magnetic field. We connect these ends to a voltmeter. We then move the wire in uniform linear motion at velocity v=0.20 m·s⁻¹ along the side b, i.e. in a direction perpendicular to the magnetic induction vector and to the side a. What voltage does the voltmeter show when the wire passes through the magnetic field?
