A flat, round iron ring 5.00 cm in diameter has a cur- rent running through it that produces a magnetic field of 75.4 mT at its center. This ring is placed in a uniform external magnetic field of 0.375 T. What is the maximum torque the external field can exert on the ring

a) electrical > light, sound, and thermal< < < <

c) both a and b.

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.
