Eddy Currents

Science > Physics > Electromagnetic Induction > Eddy Currents If a block of metal is moved in a magnetic field or kept in a changing magnetic field, the free electrons in the conductor experience force and begin to circulate. This gives rise to induced currents in closed circular paths and it is known as eddy […]
