Magnetism experiments these products support
Bar, cylindrical, horseshoe and U-shaped magnets are used to show attraction and repulsion between poles and to trace field patterns around a magnet with a magnetic needle. Keepers are supplied with the paired, horseshoe and U-shaped magnets to help them hold their magnetism in storage. The floating ring apparatus shows like poles repelling, as ring magnets on one rod hold each other apart.
The electromagnet shows that a current in a coil around a soft iron core produces a magnetic field. The Fleming's left hand rule apparatus relates the directions of field, current and force, as in an electric motor, and the right hand rule and induced current apparatus cover electromagnetic induction. The demountable transformer lets students assemble coils on a core to study transformer action and voltage ratios.
Specification examples
The Alnico Bar Magnet Pair (EL-M-10298) has its north pole clearly marked and is offered in twelve sizes from 5 to 15 cm long and 6 to 10 mm thick, supplied as a pair with keepers. The Demountable Transformer (SCL-M-11210) has a 2400-turn coil marked 220 V AC, a 130-turn coil marked 12 V AC and a 65-turn coil marked 6 V AC.
Questions about magnetism apparatus
What is the difference between chrome steel and alnico magnets?
The product pages rate chrome steel magnets as moderate in strength and alnico magnets as superior, with strong lasting power. Chrome steel bar magnets are painted red and blue to identify the poles.
Which magnets are strongest for their size?
The neodymium discs, cylinder and block are rare-earth magnets described as giving high power for their small size, with high resistance to demagnetisation. Ferrite discs and rings are the low-cost option, with high coercivity but a hard, brittle body.
What sizes do the U-shaped magnets come in?
The chrome steel U-shaped magnet is listed from 7.5 to 15 cm long in 15 x 8 mm and 15 x 6 mm sections, and the alnico version from 5 to 15 cm long with an 18 mm centre gap.
