In studies of the possibility of migrating birds using the Earth's magnetic field for navigation, birds have been fitted with coils as "caps" and "collars" as shown in the figure below. (a) If the identical coils have radii of 1.28 cm and are 2.10 cm apart, with 75 turns of wire apiece, what current should they both carry to produce a magnetic field of 4.80 x 10-5 T halfway between them? x Your response differs from the correct answer by...

A long, cylindrical conductor of radius R = 9.3 m carries a current I. The current density J, however, is not uniform over the cross-section of the conductor but is a function of the radius according to J = 15r2. Determine the magnetic field at a distance of R/2 from the center. Express your answer in microTesla.

Review. In studies of the possibility of migrating birds using the Earth's magnetic field for navigation birds have been fitted with coils as "caps" and "col- lars” as shown in Figure P30.1. (a) If the identical coils have radii of 1.20 cm and are 2.20 cm apart, with 50 turns of wire apiece, what current should they both carry to produce a magnetic field of 4.50 X...

A long cylindrical conductor of radius 54cm carries a current. The current density is not uniform over the cross section of the wire, instead is is given as J = 7r. How much current is enclosed in an Amperian loop of radius 29? Note: If we had a uniform current, then we could simply multiply a current density by an area (pi r2) to get the current. Since we are dealing with a non-uniform current, we must instead take an...
