For each case‚ find the direction of the magnetic force acting on the wire. 7. In Figure 2‚ assume that in each case the velocity vector shown is replaced with a wire carrying a current in the direction of the velocity vector. For each case‚ find the direction of the magnetic field that will produce

We use the equation F = NIlB (Force = Number of coils x Current x Length of Wire x Magnetic Field Strength) to work out the magnetic force produced in a wire when there is an electric current present. Using this equation we can see that increasing the length of the wire (amount of coils) gives a larger force. So increasing the amount of coils in an electromagnet gives a larger EMF. Variables- Independent: Length of wire‚ Number of Coils in magnet Dependent: EMF produced‚ Magnetic Field Strength
