A person is wearing a thin bracelet on a wrist that has adiameter of the bracelet, 6.2cm, and the diameter of the wire is2.0mm. The person moves the position of the hand whilst thebracelet is attached on the wrist from a position of very lowmagnetic field strength into the MRI scanner's 2.00T field with thehand pointing towards in the direction of the magnetic field.
a) Find the average emf induced in the gold bracelet, assumingit takes 0.250s to move it into the field.
b) Would the temperature of the bracelet change? Explain withcalculations.
Assume the resistivity of Gold is 2.4x10^-8 Ωm, density 19.3gcm-3 and specific heat as 0.13 kJkg^-1 K^-1
