1. Suppose the equilibrium separation of the rods is r = 4 mm, the rods are L = 15 cm long, and the current is I = 3.5 A. Use the equations in the theory section of this lab to: a) Calculate the magnetic field due to one rod at the location of the other. b) Calculate the magnetic force between the rods. c) Calculate the mass required to oppose the magnetic force. d) Calculate the required current to balance the weight of a 30 mg mass.

2. Using the same measurements of r and L as in question 1, a student measures a current of 5.9 A when she is balancing a 30 mg mass. a) What is her calculated value of μ0? b) What is the percent error between her result and the theoretical value?

Problem 1. Two horizontal parallel conducting rods are connected such that a conducting crossbar free to slide along them has a constant current I running through it (Fig. P27.34). The rods are separated by a distance l and are in an external uniform magnetic field of magnitude B directed out of the page. The crossbar has a length l and mass m. (a) In which direction will the magnetic force accelerate the crossbar? (b) If the coefficient of static friction...

If two wires carry current next to each other, they will exert a force on each other. The force is caused by magnetic fields. One current creates a magnetic field, and this field exerts a force on the other current. The magnitude of the field created by a long, straight current-carrying wire is given by Equation 1 below; B= (μ0i)/(2πr) where i is the current and r is the distance from the wire. The magnitude of the force exerted on...
