Test 4 Study Guide The Hall Effect The appearance of a transverse potential difference across a current-carrying wire in the presence of a magnetic field Allows us to determine the sign and number density of the mobile charges in a particular material The Initial Transient The electric field of the current is called Mobile electrons move opposite Polarization develops following The Steady State A transverse electric field develops pointing in the direction appropriate following polarization Calculating the Hall Effect Motional EMF Moving a wire through a magnetic field makes a current run in the wire The Initial Transient Mobile electrons inside the metal bar causes a magnetic force The polarization from the magnetic force results in an electric field inside the metal which is subjected to both an electric force and magnetic force The Steady State No current running in the bar and no net force on the bar due to the magnetic field
