2. A solid conducting disk on a shaft is rotated in an external uniform magnetic field directed parallel to theshaft. Conducting brushes are connected to the shaft and to the edge of the disk and a small lightbulb isconnected between the two brushes. The lightbulb lights when the voltage is 5.5 V. Determine how fastshould the disk be rotated to keep the lightbulb lit. The radius of the disk is 30.0 cm and the magnitude of themagnetic field is 0.60 T.Brush-bulbConducting padhBrush
