A coil with 20 turns of wire is wrapped around a tube with a cross-sectional area of 1.0 m2. A magnetic field is applied at a right angle at 0.50 T. If the coil is pulled out of the magnetic field in 5 seconds, what emf is induced in the coil?

Here you see a single loop of stiff wire, 10.0 cm on a side, immersed in a magnetic field of 0.225 T. Suppose that you remove the loop from the field in just 0.00208 sec.  What emf or voltage will be induced in the loop?  Express your answer to three significant figures and in normal notation.

The straight wire that has been bent into a perfect circle has been placed in a perpendicular magnetic field has a length of 30.0 cm. The magnetic field is changing at a rate of 13 T/s. If the resistance of the wire loop is 3.6 Ω, the electric current in the wire will be:

A wire loop with an area of 1.4×10−2 m2 is in a magnetic field of 0.36 T directed at a angle 30 to the plane of the loop. If the field drops to zero in 36 msms , what is the average induced emf in the loop?

Currents in dc transmission lines can be 100 A or higher. Some people are concerned that the electromagnetic fields from such lines near their homes could pose health dangers. For a line that has current 130 A and a height of 8.0 m above the ground, what magnetic field does the line produce at ground level? Express your answer in tes Express your answer in teslas. B = Submit Part B B BE = Submit What magnetic field does the line produce at ground level as a percent of the earth's magnetic field, which is 0.50 G. Express your answer as a percentage. ΓΕΙΑΣΦ Part C OO ΑΣΦ I Request Answer Request Answer Is this value of magnetic field cause for worry? ? T ? % No. Since this field does not differ a lot from the earth's magnetic field, it would be expected to have almost the same effect as the earth's field. Yes. Since this field does not differ a lot from the earth's magnetic field, it would be expected to have almost the same effect as the earth's field. No. Since this field is much…

A coil of 1000 turns encloses an area of 50e4 cm2 and is in a magnetic field of strength 3e-6 T which is parallel to the loops area vector. What is the induced emf if the magnetic field changes to 0 in half a minute?   5.0e-7 V 2.5e-7 V 0.005 V 0.0025 V

A coil of 15 loops of wire is laying on the table. It experiences an increasing magnetic field going into the table. If the magnetic field goes from 0.15 T to 0.85 Tin one-third of a second and the coil has a diameter of 6 centimeters, determine the magnitude of the induced EMF and the direction of the induced current

A circular loop in the plane of a paper lies in a 0.65 T magnetic field pointing into the paper. The loop's diameter changes from 21.5 cm to 6.8 cm in 0.52 s . What is the magnitude of the average induced emf?

A 0.300 mm diameter copper wire makes up a 85.0 turns, 7.90 cm diameter coil. There is a magnetic field parallel to the axis of the coil. If the induced current in the coil is 4.80 A, what is the rate of change of the magnetic field? 58.5 T/s 4.97×103 T/s 3.20×10-6 T/s 0.222 T/s

A fixed 17.4-cm-diameter wire coil is perpendicular to a magnetic field 0.56 T pointing up. In 0.29 s , the field is changed to 0.35 T pointing down. What is the average induced emf in the coil?
