A coil of many circular turns of insulated copper wire wound on a cylindrical insulating body such that its length is greater than its diameter is called solenoid. When current is flowing through it, the magnetic field line pattern resembles exactly with those of a bar magnet with fixed polarity.1. What is the use of current carrying solenoid?a. It is used to distribute powerb. It is used to form a temporary magnet called electromagnetc. It is used to generate electricityd. It is used in nuclear reactions2. The current carrying solenoid behave as a bar magnet. True or false?a. TRUEb. FALSE3. ______ the solenoid magnetic field is minimum.a. Insideb. Outsidec. On the boundaryd. Everywhere4. What happens to the magnetic strength in the centre of solenoid?a. It remains the sameb. It becomes doubledc. It becomes halvedd. It becomes tripled5. At which point is the strength of solenoid maximum?a. Insideb. Outsidec. Both A and Bd. None of the above
