A wire loop with a resistance, R = 0.174 Ohms is pulled to the right out of a region with a uniform magnetic field B = 0.468 T  that points out of the screen as shown in the diagram below. As is moves, out of the field region, a current is induced, because of the current, there is a magnetic force on the loop. How much force (magnitude only) is required to keep the loop moving at a constant speed of v = 17.0 m/s? The height of the loop, L = 0.189 m. Please give your answer in Newtons.

Electromagnets

The word "electromagnet" is composed of two words, ‘electro’ and ‘magnet’. It is a type of magnet in which an electric current helps in the generation of a magnetic field. Electromagnets usually consist of two major parts, wire and a coil around which the wire is wound. This is called a solenoid. When an electric current is allowed to pass through the coiled wire, the electric current produces a magnetic field. This magnetic field is present only when current is passing through the wire.
