Use the data from Table 24.1 to determine at what approximate distance from a wire carrying a current of \(10 \mathrm{~A}\) the magnetic field strength would equal that of a refrigerator magnet.

TABLE 24.1 Typical magnetic field strengths Field source and location 10 cm from a wire with 1 A current Field strength (T) 2 x 106 Surface of the earth 5 x 10-5 1 cm from a wire with 10 A current 2 x 10+ Refrigerator magnet 5 x 103 100-turn coil, 1 cm diameter, with 1 A current 1 X 10-2 Surface of the sun, 1 X 101 in a sunspot Near a rare-earth magnet MRI solenoid 1 1
