Calculating magnetic flux, induced current & magnetic field

Reference no: EM1313003

Question: An ideal solenoid produces a magnetic field of B = 3.0? 10-3 T when it carries a current of 3.0 A.

[A] Find the number of turns of wire per length of solenoid.

n = __________units

[B] (5%) The magnitude of the induced emf in the wire loop is E = 0.05 V. What is the magnitude of the rate of change of the magnetic field in the solenoid?

db/dx ____________units.

[C] A square loop of wire is placed inside the solenoid, perpendicular to the magnetic field as shown in the sketch. The length of one side of the square is 0.040 m, & the magnetic field is still B = 3.0? 10-3T. Find the magnetic flux through the square loop.

ØB = ________________units

[D] (5%) The x's on the sketch above indicate that the magnetic field points into the page. The magnetic field is made to increase with time, & a current is induced in the wire loop. Draw an arrow on the wire loop that shows the direction of the induced current.
