1 Physics Mrs. Coyle

2  Lorentz Force- Magnetic Force on a Current Carrying Wire (Fendt Applet) Lorentz Force- Magnetic Force on a Current Carrying Wire

3 F=BILsin   I: current (conventional)   angle between I and B When  =90 o, then F=BIL F

4  A wire 86cm long is carrying a current of 0.25A at right angles to a uniform magnetic field of 15T.  Find the magnitude of the magnetic force.  Answer: 3.3N

5 What is the direction of the magnetic force acting on this wire? I Answer: Upwards
