Patterns of Magnetic Fields A magnet field is produced when a current flows through a wire i.e. a current-carrying conductor produces a magnetic field. Straight Wire: Using a plotting compass the magnetic field pattern can be drawn. Place a wire upwards through a...
magnetic materials are attracted to the two ends of a magnet, called the poles; magnets have two poles, the south and north pole, the north-seeking pole points to the north and the south-seeking pole to the south; like poles repel and unlike poles attract.
A magnetic material is any material which feels a force when placed in a magnetic field e.g. cobalt, nickel, and a few alloys such as steel. A non-magnetic material is any material which does not feel a force when placed in a magnetic field e.g. brass, copper,...
