Today’s agenda: Magnetic Fields Due To A Moving Charged Particle. You must be able to calculate the magnetic field due to a moving charged particle. Biot-Savart Law: Magnetic Field due to a Current Element. You must be able to use the Biot-Savart Law to calculate the magnetic field of a current- carrying conductor (for example: a long straight wire). Force Between Current-Carrying Conductors. You must be able to begin with starting equations and calculate forces between current- carrying conductors.

Magnetic Field of a Current-Carrying Wire “Knowledge advances when Theory does battle with Real Data.”—Ian Redmount It is experimentally observed that parallel wires exert forces on each other when current flows. I1I1 I2I2  F 12 F 21 I1I1 I2I2  F 12 F 21

Example: use the expression for B due to a current-carrying wire to calculate the force between two current-carrying wires. I1I1 I2I2  F 12 d L L2L2 L1L1 B2B2  The force per unit length of wire is Homework Hint: use this technique for any homework problems with long parallel wires! x y z

I1I1 I2I2  F 12 F 21 d L L2L2 L1L1 B1B1  The force per unit length of wire is B x y z

Be able to show that if the currents in the wires are in the opposite direction, the force is repulsive. I1I1 I2I2  F 12 F 21 d L L2L2 L1L1 The official definition of the Ampere: 1 A is the current that produces a force of 2x10 -7 N per meter of length between two long parallel wires placed 1 meter apart in empty space.
