4. A long straight wire carrying a current is in the plane of a circular loop of wire. The current is decreasing. Both the loop and the wire are held in place by external forces. The loop has a resistance of 24. -Long wire Conducting loop a) In what direction does the induced current in the loop flow? Mint: first find the external magnetic field at the loop due to the long wire, figure out if the flux through the...

The figure below shows a cross-section of two long, straight,
parallel wires, where the currents are flowing perpendicular to the
page. Wire 1 carries a current
I1
directed into the page (in the
−z
direction) and passes through the x-axis at
x = +a.
Wire 2 passes through the x-axis at
x = −2a
and carries an unknown current
I2.
The total magnetic field at the origin due to the
current-carrying wires has the magnitude
2μ0I1

a) a horizontal long straight wire carries a current of I1= 8A from left to right. The wire is tangential to a circular loop of wire of Radius R= .03 m lying immediately below it. The loop carries a current of l2= 2A in the counter clockwise direction. Assuming that the thickness of the wires are negligible, find the magnitude and direction of the net magnetic field at the center of the circular loop b) a second long wire also...
