Calculating Forces on Wires Two wires, both carrying current out of the page, have a current of magnitude 5.0 mA. The first wire is located at (0.0 cm, 3.0 cm) while the other wire is located at (4.0 cm, 0.0 cm) as shown in Figure 12.10. What is the magnetic force per unit length of the first wire on the second and the second wire on the first? (b) The movements of M 1 to the right and of M 2 to the left release rope allowing M 3 to move down. M 3 moves down by a distance which is half of the total length of rope made available by M 1 and M 2. Let (x 1, x 2) be the displacement of (M 1, M 2) to the (right, left). Let y 3 be the displacement of M 3 downward. Then (x 1 + x 2) / 2 = y 3
In one form of Tesla coil, a long solenoid with length L and cross-sectional area A is closely wound with N1 turns of wire. A coil with N2 turns surrounds it at its center. (a) (10 pts) Find the mutual inductance. (b) (15 pts) Suppose the current i2 in the outer, surrounding coil is given by i2 = (2.0 x 106 A/s) t. At Figure this: the same man who guaranteed a surprise outbreak of a virus in the next two years, gave almost 4 million Now that the announced pandemic is indeed here, the same Rockefeller Foundation came forward with step two: a They discuss how to build an army to carry out this control system.
Jun 09, 2019 · b)both the length and the radius of the wire are doubled c)the radius of the wire is doubled. d)the length of the wire is doubled. Ans. 2.The temperature coefficient of resistance of a wire is 0.00125 per°C- At 300 K, its resistance is 1 ohm. This resistance of the wire will be 2 ohm at  a)1154 K b) 1100 K c) 1400 K d) 1127 K Ans.
