Moving Charges & Magnetism Topic Based Quiz (Magnetic Dipole Moment of Current Carrying Loop) General Instructions This quiz belongs to the Chapter- Moving Charges & Magnetism This quiz is based on the concept of- Magnetic Dipole Moment of Current Carrying Loop Each question carries one mark. There is no negative marking. Keep a rough notebook with you for rough work. All the best! 1. Two wires of same length are shaped into a square and a circle. If they carries the same current, the ratio of their magnetic moments will be- 2 : π π : 2 π : 4 4 : π None 2. Assertion- When radius of a circular loop carrying a steady current is doubled, its magnetic moment becomes 4 times.Reason- The magnetic moment of a circular loop carrying a steady current is proportional to the area of the loop. Both Assertion and Reason are true and Reason is the correct explanation of Assertion Both Assertion and Reason are true but Reason is not the correct explanation of Assertion Assertion is true but Reason is false Both Assertion and Reason are false None 1 out of 2 Time's up Share with your friends here!
