How can an intensely hot Sun be magnetic?
I am, a student of STD 9 from India. I was going through your website and was highly benfitted by it. But I got a query .. How can the Sun be magnetic when its surface temperature itself is about 6000 degree Celsius ? And what is the proof that this magnetism is present on earth ? If it is present, how come it does not induce magnetism in all ferromagnetic substances ? Reply From your e-mail I can see that you have reached “The Great Magnet, the Earth” but have not gone very far in it. Please do so now! You will find that magnetism in nature is primarily produced by electrical currents, not by ferromagnetic substances like magnetized steel. There is no limit to the temperatures at which electrical currents can flow–on the contrary, at high temperatures electrons are torn off atoms, and the resulting plasma (see http://www.phy6.org/ Education/wplasma.html) can conduct electrical currents with very little resistance. The questions you have asked were already raised by others. Interestin
