Question

During a lab experiment, Bhavna uses a solenoid connected to a battery. She notes down the following facts: (i) The pattern of magnetic field lines inside the solenoid is similar to a bar magnet. (ii) The north pole and south pole of the current-carrying solenoid can be identified by applying the right hand thumb rule. (iii) A solenoid can be used to magnetise a piece of soft iron, making it an electromagnet.

Choose the option enlisting all the correct statements:

Accepted Answer

D. All three statements are correct. The magnetic field of a solenoid resembles that of a bar magnet, polarity can be determined by the right-hand thumb rule (or clock rule), and placing a soft iron core inside creates an electromagnet.
