Question

1)in the figure below and electric field is directed out of the page within a circular region of radius R=2.75cm. the field magnitude is E=(0.410 v/m*s)(1-r/R)t where the t is in seconds and the r is the radial distance

a) what is the magnitude of the induced magnetic filed at a radial distance of 2cm?

b)what is the magnitude of the induced magnetic filed at a radial distance of 5cm?

Answer #1

The figure shows a circular region of radius R = 4.17 cm in
which an electric flux is directed out of the plane of the page.
The flux encircled by a concentric circle of radius r is given by
E,enc = (0.600 V·m/s)(r/R)t, where r ≤ R and t is in seconds. What
is the magnitude of the induced magnetic field at radial distance
2.17 cm? 1.325*10^17 T is wrong

There is a uniform electric flux perpendicular to a circular
region of radius R = 2.2 cm. The electric flux is only contained
within the circular region, and the total value can be expressed by
the following function: ΦE = 5.3t, where ΦE is in V⋅m when t is in
seconds. At a radial distance of 4.0 cm from the center of the
circle, what is the magnitude of the induced magnetic field?
Express your answer in fT (femtoteslas). Femto-...

Suppose that you have a circular magnetic field ‘B’ of radius R
= 9.0 cm, pointing inside the page and if this field is increased
at the rate dB/dt = 0.15 T/sec. calculate (a) the magnitude of
induced electric field at a point within the magnetic field at a
distance r =5.0 cm, from the center of the field and (b) the
magnitude of the induced electric field at a point out side the
magnetic field at a distance r...

a) There is a uniform electric flux perpendicular to a circular
region of radius R = 2.8 cm. The electric flux is only
contained within the circular region, and the total value can be
expressed by the following function: ΦE =
6.3t, where ΦE is in V⋅m when
t is in seconds. At a radial distance of 4.9 cm from the
center of the circle, what is the magnitude of the induced magnetic
field? Express your answer in fT (femtoteslas)....

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.

A circular area of radius R=8.5 cm has a magnetic field into the
page. This field is time-varying such that dB/dt = 0.13 T/s. Take
the positive direction to be into the page, and assume an idealized
field that is zero immediately outside R. (a) Describe the Electric
field generated by this time-varying B-field (draw a diagram). (b)
Find an expression for the magnitude of E of the induced electric
field for r < R. Evaluate at r=5 cm. (c)...

A 37-turn circular coil of
radius 4.60 cm and resistance 1.00 Ω is placed
in a magnetic field directed perpendicular to the plane of the
coil. The magnitude of the magnetic field varies in time according
to the expression B = 0.010
0t + 0.040 0t2,
where B is in teslas and t is in
seconds. Calculate the induced emf in the coil
at t = 4.20 s.

Uniform displacement-current density. The figure shows
a circular region of radius R = 3.70 cm in which a
displacement current is directed out of the page.The displacement
current has a uniform density of magnitude

magnitude of the magnetic field due to the displacement current at
radial distances (a) 1.40 cmand
(b) 4.50 cm?

The induced magnetic field at radial distance 6.0 mm from the
central axis of a circular parallel-plate capacitor 1.7 × 10-6 T.
The plates have radius 3.8 mm. At what rate is the magnitude of the
electric field between the plates changing?

In the figure below, a long circular pipe with outside radius
R = 2.20 cm carries a (uniformly distributed) current
i = 13.5 mA into the page. A wire runs parallel to the
pipe at a distance of 3.00R from center to center. Find
the (a) magnitude and (b)
direction (into or out of the page) of the current in the wire such
that the ratio of the magnitude of the net magnetic field at point
P to the magnitude...
