When an alternating emf is applied to the primary coil, a changing current flowing in it produces an alternating magnetic flux in it. Like poles repel each other while unlike poles attract each other. iii. Heating and Lighting Effect of Current Electricity. Magnetic lines of force never intersect each other. MAGNETISM AND ELECTRICITY. We know that electric current is the result of the flow of electrons. Magnetic force of lines are continuous curve because magnetic lines of force starts at north pole and ends at south pole externally whereas south pole to north pole internally. Selina Concise ICSE Solutions for Class 7 Physics Chapter 7 Electricity and Magnetism. Items that do not get attracted to magnets are called non-magnetic. Electricity and Magnetism – Notes.
