A metal rod is connected to a battery through two stiff metal wires that hold the rod horizontally. The rod is between the poles of a horseshoe magnet that is sitting on a mass-measuring platform scale, which reads 100.0 gg. After you turned on the current in the circuit, the scale supporting the magnet read 106.0 gg. The part of the rod that is exposed to the magnetic field is 6.0 cmcm long and the current through it is 1.5 AA.
Find the magnitude of the magnetic field.

Magnetic levitation A metal rod of length w = 15 cm and mass m = 85 grams has metal loops at both ends, which go around two metal poles (see the figure). m = mass of red ------ ------- The rod is in good electrical contact with the poles but can slide freely up and down. The metal poles are connected by wires to a battery, and a current I = 3 amperes flows through the rod. A magnet supplies...

Two long, straight, conducting wires are both
perpendicular to the xyxy-plane. Wire 1 passes through the point xx
= 0, yy = 1.00 cmcm, zz = 0 and carries current 1.00 AA in the
+zz-direction. Wire 2 passes through the point xx = 0, y = -1.00
cmcm, zz = 0 and carries current 4.00 AA also in the +zz-direction.
Find the net magnetic field due to both wires at xx = 0, yy = 0, zz
= 0.
