PHYS 1502Q Chapter 14: 14: Biot-Savart Law
Document Summary
Magnetic field due to infinitely long straight current carrying wire. Magnetic forces between two parallel current carrying wires on each other. Magnetic field on the axis of a circular current carrying loop. Magnetic fields are produced by flowing currents ds r . 0 sd is in the same direction of current r is from to point p. Bd = 4 (biot-savart law) only gives the magnetic field at point p due to a segment r2 sd current of the wire. An integral is needed to determine the total magnetic field at point p. B = r = r cos sin ds z. 4 x ds r r2 d = d = r s cos 2. 2 cos r r2 cos 2 d z tan x = r. Rhr (b field at any point r away from a current carrying wire is tangential to the circle with radius r)
