I,

Two parallel wires are separated by 1.16 mm. Wire A carries 2.59 A and Wire B carries 8.32 A (both currents in the same direction). Calculate the force on 6.19 m of Wire A.

Two long, parallel wires separated by 2.90 cm carry currents in opposite directions. The current in one wire is 1.30 A, and the current in the other is 3.20 A. (a) Find the magnitude of the force per unit length that one wire exerts on the other. N/m (b) Is the force attractive or repulsive? attractive repulsive

Two parallel wires are separated by 5.75 cm, each carrying 2.75 A of current in the same direction. (a) What is the magnitude of the force per unit length between the wires? N/m (b) Is the force attractive or repulsive? attractive O repulsive

9. A helium nucleus (2 protons, 2 neutrons) is traveling at a velocity of 4.33 x 10^6 m/s a distance of 4.52 cm away from a wire carrying a current of 1.40 A. The helium nucleus is traveling in a direction parallel to the current in the wire. How much acceleration does the helium nucleus experience due to the magnetic force from the current in the wire?     1.54E+09 m/s^2   2.05E+09 m/s^2   1.28E+09 m/s^2   5.12E+08 m/s^2

A straight wire in a magnetic field experiences a force of 0.032 N when the current in the wire is 1.5 A. The current in the wire is changed, and the wire experiences a force of 0.074 N as a result. What is the new current?

Wire 1 carries 1.40 A of current north, wire 2 carries 3.40 A of current south, and the two wires are separated by 1.40 m. 1)Calculate the magnitude of the force acting on a 1.00-cm section of wire 1 due to wire 2. (Express your answer to three significant figures.)
