QUESTION 3 An outline of the features of a DC motor is shown in the following diagram. It consists of a loop conductor in a magnetic field. A commutator connects the loop to a DC supply. (3 marks) 0 050 m Length AB = 0.60 m, and the length of the conductor in the magnetic field is 0.050 m. The magnetic field strength is 0.25 T and a current of 10 A flows in the loop. A) In which direction will the coil rotate? B) What is the purpose of the commutator? C) What is the maximum force acting on the section of wire AB? ​
