A copper wire has a diameter of 1.29x10^-3m. It carries a current density of 7.65x10^6A/m^2, which is assumed to be uniform over the cross section. (a) Calculate the current in the wire. (b) The copper has a conductivity of 5.8x10^7A/Vm with such a wire of 1 mile long, determine the resistance of the copper wire. (c) Determine the potential difference between the two ends of the wire with the current and resistance. (d) Determine the field intensity of E in...
In the diagram below, the long straight wire carries a current
to the right and the current is increasing with time. This changing
current produces an emf in the circular loop. What is the direction
of the induced emf?

18.3) Straight wire A long straight wire carries a current I(t) = I0e-kt. A rectangular loop of dimensions a x b is a distance d below the wire. Find the induced emf in the loop. What direction is the induced current?
An infinite straight wire carries current I1 = 3 A in
the positive y-direction as shown. At time t = 0, a conducting
wire, aligned with the y-direction is located a distance d = 50 cm
from the y-axis and moves with velocity v = 12 cm/s in the negaitve
x-direction as shown. The wire has length W = 24 cm.

You have a piece of copper (conductivity = 6.0*10^7 Ω^-1m^-1) wire 26 cm long and 2.0 mm in diameter and a bar magnet with a magnetic dipole moment of 0.75 Am^2. You decide you’re going to make use of induction to make some current flow in the wire. First, you pull the copper wire into a circular loop. Then you hold the bar magnet 15 cm above the center of the loop, parallel to the loop so that there is...
