Question

Part A

At what distance from a very thin, straight wire carrying a 25 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 25 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 25 A current would the magnetic field strength of 1T be generated?

Part D

At what distance from a very thin, straight wire carrying a 25 A current would the magnetic field strength of 10T be generated?

Here ,

as the magnetic field due to thin straight wire is given as

B = u0*I/(2*pi*d)

part A)

let the distance is d

B = u0*I/(2 *pi * d)

5 *10^-5 = 4pi *10^-7 * 25/(2pi * d)

solving for d

d = 0.1 m

the distance from the thin wire is 0.1 m

part B)

B = u0*I/(2 *pi * d)

5 *10^-3 = 4pi *10^-7 * 25/(2pi * d)

solving for d

d = 0.001 m

the distance from the thin wire is 0.001 m

part C)

B = u0*I/(2 *pi * d)

1 = 4pi *10^-7 * 25/(2pi * d)

solving for d

d = 5 *10^-6 m

the distance from the thin wire is 5 *10^-6 m

part D)

B = u0*I/(2 *pi * d)

10 = 4pi *10^-7 * 25/(2pi * d)

solving for d

d = 5 *10^-7 m

the distance from the thin wire is 5 *10^-7 m
