Magnetic effects of Magnetic current Notes chapter 13 Physics class 10
Magnet: Magnetic field and magnetic field lines, Magnetic field due to a current carrying conductor, Right hand thumb rule, Magnetic field due to current through a circular loop. Magnetic field due to current in a solenoid. Magnet is an object that attracts objects made of iron, cobalt and nickle. Magnet comes to rest in North – South direction, when suspended freely. Use of Magnets: Magnets are used in refrigerators. in radio and stereo speakers. in audio and video cassette players. in children’s toys and; on hard discs and floppies of computers. Properties of Magnet : A free suspended magnet always points towards the north and south direction. The pole of a magnet which points toward north direction is called north pole or north-seeking. The pole of a magnet which points toward south direction is called south pole or south seeking. Like poles of magnets repel each other while unlike poles of magnets attract each other. Magnetic field: The area around a magnet where a magnetic
