1. The problem statement, all variables and given/known data 1. Oersted discovered that a curernt carrying wire caused a magnet to move. Why does the magnet move? 2. Ampere discovered that a magnet caused a current carrying wire to move. Why does the wire move? 2. Relevant equations (i) ∫Edl = - dΦ_B/dt (ii) ∫Bdl = Iμ_0 + μ_0ε_0(dΦ_E/dt) (iii) F = qvxB (iv) F = IBxL 3. The attempt at a solution 1. By eq. (i), a changing electric field will result in a change in magnetic flux i.e. will induce a magnetic field. This magnetic field will react with the magnetic field of the magnet, causing it to move. 2. By eq. (ii), a changing magnetic field will result in a change in electric flux i.e. will induce an electric field. This will react with the electric field of the current-carrying wire, causing it to move. Do you think these answers are sufficient? Is there anything more to be said?
