Question

Ordinary rubber is an insulating. but the special rubber tyres of aircrafts are mage slightly conducting. why this is necessary

Answer 1

This is because when the aircraft tyre moves at high speed due to the process of conduction it gets charged. So the tyre is made conducting to ensure that the charge returns to the surface and there is no accident due to developing charge in tyre. If it was non conducting then the charge would stay there.

Answer 2

Answer:

Rubber magnets are molded by mixing rubber with ferrite powder. The absorption power is substantially weaker than anisotropic ferrite magnets, but machining can be performed easily after purchasing these products, as they can be cut with a pair of scissors or cutters.
