Calculate the current carried in a 175-turn circular loop 18.0 cm in diameter to create a maximum torque of 27 N-m if the strength of the magnetic field in which the loop rotates is 1000 times that of the Earth. (Recall that Earth's magnetic field has an average strength of 10T A . 152A B. 0.152 A C. 152 A D. 152 A Barbara is hiking and carrying a navigational compass, and she walks beneath an overhead transmission line approximately 6.00 m above the compass. The current in this transmission line is 1.00 kA. Determine the strength of the magnetic field at Barbara's compass. A. 33% 10~ L 1305 21078 T B. 6.7x107 T D. 1.0x104T
