Magnet and its properties
WebIt can even become a permanent magnet if exposed to the right magnetic fields. This was an invaluable property for early humans and navigation. It’s thought that naturally occurring magnets formed from magnetite were how humans originally discovered magnetism. The Lodestone. A naturally occurring magnetite magnet is generally called a lodestone. WebThe magnitude of the electric field outside the sphere at any radial distance r from the center is 3 k q / r ^ { 2 } 3kq/r2 (with q > 0), directed toward the center, and the charge on the inner surface of the sphere is -2q. What are (a) the charge on the particle and (b) the charge on the sphere? Verified answer.
