Question

What is the Magnetic Field created by a wire, at a distance of 0.4 m, when a current of 490 amps is flowing in the wire?

If a Magnet ( B = 2 T. ) falls through a loop of radius 0.14 meters. If it takes 0.11 seconds to fall , what is the maximum induced voltage? Answer as a positive voltage.

Answer #1

Find this solution .if any issue with that don't forget to write in
comment section.I will rectify them as soon as possible.

If you find the solution helpful and kindly RATE THE ANSWER it
would be appreciated.

Your rating is important to me.

Thanks for asking..

A loop of wire sits in a uniform magnetic field, everywhere
pointing toward you. Due to a changing magnetic flux through the
loop, an induced current flows in the wire, clockwise as shown. The
area of the loop is J. 1.63 m2 , and the magnetic field initially
has magnitude K. 0.61 T.
(a) Suppose that, over a time period of L. 1.47 s, the magnetic
field changes from its initial value, producing an average induced
voltage of M. 8.7...

Written Problem: Induction from a falling
magnet
We have a small magnet with a magnetic moment of m = 0.1
Am2 (remember: magnetic moment is defined as m = IA -
see page 932 of book for the definition). We also have coils of
wire. The coils are made out of 100 circular loops of a single
wire. A single loop has a radius of 10 cm. The thickness of the
wire has a circular cross section with a 0.5...

A magnetic field, strength 3T, has a direction out of the page.
A loop of wire sits in the field and on the plane of the page (area
vector of loop is out of page). The loop is much smaller than the
extent of the field. The magnetic field starts to slowly change at
a rate of -0.0001T/s. Looking down on the loop, which statement is
correct?
A. Magnetic flux out of page decreasing; anti-clockwise current
induced in loop
B....

6: A single-turn circular loop of wire rests flat on this page.
A magnetic field is directed perpendicular to this page pointing
outwards (towards you). When the magnetic field strength increases
from 3.2 T to 6.5 T in 0.026 seconds, a 1 V emf is induced in the
coil.
a) Calculate the radius of the loop.
b) State the direction of the induced current and briefly
explain how you arrived at your answer.

field. The magnetic flux through the loop is 24 mWb. What is the
radius of the loop?

A circular wire loop with a radius of 10 cm is placed in a
magnetic field of 1.0 T that is parallel to its axis into the page.
The loop is stretched to half of its initial area within a time of
0.1 seconds. What is the induced voltage and the direction of
induced current?
(a) 157 mV, clockwise current
(b) 120 mV, counter clockwise current
(c) 79 mV, clockwise current
(d) 0 V, no current
The answer is A...

A circle with a radius of 0.4 meters is placed in the
x-y plane in a magnetic field directed in the -z direction. It is
wound once and its resistance is 6 Ohms. The initial magnetic field
is 0.6 Tesla. The magnetic field is then changed in 0.7 s and the
average induced current is 0.03 amps running counter-clockwise.
First, find the final magnetic field to needed to induce this
average current.
Then, the magnetic field (still in the -z...

Consider a rectangular "loop" of iron wire that is placed in a
uniform magnetic field of magnitude 29T pointing in the
positive z -direction.
At t= 4s , the ring is sitting in a magnetic
field pointing in the positive z -direction whose
magnitude changes linearly from 15T at
t= 4s to 26T at
t= 9s . In which direction does the induced
magnetic field coming from the induced current in the ring point at
t= 6.5s ?
In the positive x
-direction.
In the negative x
-direction....

A magnetic field is passing through a loop of wire whose area is
0.014 m2. The direction of the magnetic field is
parallel to the normal to the loop, and the magnitude of the field
is increasing at the rate of 0.29 T/s. (a)
Determine the magnitude of the emf induced in the loop.
(b) Suppose the area of the loop can be enlarged
or shrunk. If the magnetic field is increasing as in part
(a), at what rate (in...

A
physicist measures the magnetic field at the center of a loop of
wire with N number of turns (not a solenoid) and current I flowing
through it. They then triple the number of coils and half the
radius of the coil while keeping the current the same. How does the
magnetic field compare in the new situation, B2, compared to the
first measurement, B1?
