QUESTION 21 The diagram below shows two parallel wires with the top wire carrying a steady current of 2.00 A and the bottom wire carrying a steady current of 5.00 A both running in opposite directions. If the wires are separated by a distance of 2.00 cm, what is the magnetic field strength at a point 3.00 cm below the bottom wire? I = 2.00 A 2.00 cm I2 = 5.00 A 3.00 cm

answer should be in cm

Two long parallel wires 20 cm apart carry currents of 5.0 A and 8.0 A in opposite directions. What is the magnitude of the net magnetic field midway between the wires? O 1.3 x 10-5 T 1.0 x 10-5 T 2.6 x 10-5 T 6.0 x 10-6 T 1.6 x 10-5 T

The magnitude of the magnetic field 70.0 cm from a long, thin, straight wire is 8.0µT. What is the current through the long wire? A

A 3.0 cm section of a horizontal wire carrying a 6.7 A current from east to west is place in a north to south 0.42 T magnetic field in the lab. In what direction is the magnetic force on the 3.0 cm section? north south up down southwest

A wire carries an I1 = 7.45-A current along the x-axis, and another wire carries an I2 = 5.00-A current along the y-axis, as shown in the figure below. What is the magnetic field at point P, located at x = 4.00 m, y = 3.00 m? magnitude      Use the expression for the magnetic field around a current-carrying wire to find the magnitude and direction of the magnetic field contribution from each of the two currents. µT direction              Two current-carrying wires lie along the axes in the x y coordinate plane. The wire along the x-axis carries current I1 in the +x-direction and lies on top of the wire along the y-axis, which carries current I2 in the +y-direction. Point P is in the first quadrant at (4.00, 3.00) m.
