# Moving Charges and Magnetism

Subject matter experts of JagranJosh have developed chapter wise practice questions of Class 12th as per the relevancy of the chapter in the CBSE board exam. This practice set contains 10 questions with detailed explanations on “Chapter: Moving Charges and Magnetism” of Physics.

• Q1.If a particle is moving in a uniform magnetic field, then

• Q2.A length of wire carries a steady current. It is bent first to form a circular plane coil of one turn. The same length is now bent more sharply to give a double loop of smaller radius. The magnetic field produced at the centre produced by same current is:

• Q3.A conductor carrying a current i is shown in the figure given below. The magnetic induction at the centre O is:

• Q4.To convert a galvanometer into an ammeter, we connect

• Q5.Two similar conductors carrying same amount of current are placed as shown in the figure given below. The plane on one conductor is along x-axis and other is along y-axis. What is the ratio of resultant magnetic field at a common point to the individual magnetic field?
