A force is exerted on a magnetic material brought into a magnetic field. The force is a non-contact force because the magnet and the material do not have to touch each other.]]> 2018-06-24 06:56:43 UTC https://padlet.com/yasmeensakiren2003/e8tamk5f34qs/wish/268323631 yasmeensakiren2003 https://padlet.com/yasmeensakiren2003/e8tamk5f34qs/wish/268323830 2018-06-24 07:04:50 UTC https://padlet.com/yasmeensakiren2003/e8tamk5f34qs/wish/268323830 yasmeensakiren2003 https://padlet.com/yasmeensakiren2003/e8tamk5f34qs/wish/268324906 2018-06-24 07:38:23 UTC https://padlet.com/yasmeensakiren2003/e8tamk5f34qs/wish/268324906 yasmeensakiren2003 https://padlet.com/yasmeensakiren2003/e8tamk5f34qs/wish/268328906 Magnets have a north pole and a south pole.

Magnets attract steel because it contains iron. Magnetism is one aspect of the combined electromagnetic force. It refers to physical phenomena arising from the force caused by magnets, objects that produce fields that attract or repel other objects.]]> 2018-06-24 09:24:46 UTC https://padlet.com/yasmeensakiren2003/e8tamk5f34qs/wish/268329024 yasmeensakiren2003 https://padlet.com/yasmeensakiren2003/e8tamk5f34qs/wish/268329820 Hence,when we took the other magnet and bring it nearer to the coins,the coins moved as well due to magnetic field and magnetism. The magnet did not touch the coins which means it is a non-contact force.The coins moved as it was made out of steel(which hv iron),copper and nickel due to the force caused by the magnets. Therefore,i assure that this is a physics phenomenon as it involves the pull and push of magnetic forces.]]> 2018-06-24 09:47:06 UTC https://padlet.com/yasmeensakiren2003/e8tamk5f34qs/wish/268329820
