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.

(b) Write symbolic expressions for the current through resistors R and 2R immediately after the switch

John is using a cordless electric weed trimmer with a dc motor to cut the long weeds in his backyard. During normal operation the trimmer generates a back emf of 16 V when it is connected to an emf of 24 V dc. The total electrical resistance of the motor is 8.0 Ω. (a) How much current flows through the motor when it is running smoothly? (b) Suddenly the string of the trimmer gets wrapped around a pole in the ground and the motor quits spinning. What is the current through the motor now? (c) How does the amount of heat dissipated in the motor during normal operation compare to the amount of heat dissipated when the motor is stuck? Calculate the ratio of the two amounts.
