Answer #1

Find the number of turns per metre using the number of turns and length of solenoid as shown below. Use equation for magnetic field inside a long solenoid to find the required current.no. of turns per meter is, n = 1150 = 0-42m 2738.1 turns/m Magnetic field B = Mon I 3 1.0X10-4T = Mo [2738.1 tums/m) I 3) I =
