Question

Item 6

Part A

At what distance from a very thin, straight wire carrying a 11 A current would the magnetic field strength of 5.0×105T be generated?

Part B

At what distance from a very thin, straight wire carrying a 11 A current would the magnetic field strength of 5.0×103T be generated?

Part C

At what distance from a very thin, straight wire carrying a 11 A current would the magnetic field strength of 1T be generated?

Part D

At what distance from a very thin, straight wire carrying a 11 A current would the magnetic field strength of 10T be generated?

Explanation / Answer

Magnetic field = uoI / 2pi*r

where r = distance from the wire

A) 5*10^-5 = 4pi*10^-7*11 / 2pi*r

r = 0.044 m

B)

5*10^-3 = 4pi*10^-7*11 / 2pi*r

r = 0.044 *10^-2 m

C) 1 = 4pi*10^-7*11 / 2pi*r

r = 2.2*10^-6 m

D) 10 = 4pi*10^-7*11/2pi*r

r = 2.2*10^-7 m
