U-shaped magnet red green

8cm high horseshoe magnet with south and north poles clearly identified with different colors. Ideal to discover magnetic fields.
The educational Alnico magnets are made of an aluminium, nickel, and cobalt alloy. This alloy is known to offer powerful magnetic properties when it is electrically charged.Although these magnets are less powerful than neodymium/iron/boron magnets (NdFeB magnet), they are less brittle and can resist higher temperatures up to 450°C.

Poles are coloured: the north pole is red, the south pole is green.
Two opposite poles attract each other. Identical poles repel each other.

North and south poles are clearly identified : It is the prefect tool to discover magnetic fields, at home or at school.
