Expert Solution
here,we just provided with magnetic
field,area and angle between the area vector and magnetic
field.then we find the magnetic flux in weber by the expression of
magnetic flux,with the diagram.
A square loop of wire with sides of length 34 cm is in a uniform
magnetic field perpendicular to its area.
Part A
If the field's strength is initially 110 mT and it decays to
zero in 0.011 s , what is the magnitude of the average emf induced
in the loop?
Part B
What would be the average emf if the sides of the loop were only
17 cm ?
Express your answer using two significant figures.
a) How does the magnetic flux through
the loop changes as the magnet rotates. Is the flux maximal when
the magnet is horizontal or vertical on the screen?
Why?
b) How does changing the magnetic flux
works to create an emf (potential difference) in the coil, which
alternates over time (use the Faraday’s law
equation)?

A)If BB = 1.0 TT, then the angle between the B⃗ B→ field and
the normal to the loop's surface is greater than 0∘∘.
B)If the direction of B⃗ B→ field is parallel to the normal to
the loop's surface, then BB = 0.8 T.
C)The magnitude of the B⃗...
When a DC current passes through the coil, it will produce a
magnetic flux around the coil. Is this the reason why the coil get
heated? Because the magnetic flux will be stable after all as DC
current does not oscillate?

A 20-cmcm-diameter circular loop of wire is placed in a 0.64-T
magnetic field.
a) When the plane of the loop is perpendicular to the field
lines, what is the magnetic flux through the loop?
Express your answer to two significant figures and include the
appropriate units.
b) The plane of the loop is rotated until it makes a

A single loop of wire with an area of 0.0900m2 is in a uniform
magnetic field that has an
initial value of 3.8 T, is perpendicular to the plane of the loop,
and is decreasing at a
constant rate of 0.190 T/s. (a) What emf is induced in this loop? (b) If the loop has a resistance of 0.600O, find the current induced in the loop.
A loop of wire has a radius of 2.0 cm and is in a constant
magnetic field of 0.88 T directed into the plane of the paper. If
the loop collapses so the radius of the circle shrinks to zero in a
time of 0.35 s, a) find the magnitude of the average induced emf in
the loop. b) If the loop is part of a larger circuit, in which
direction does the induced current flow as the loop closes.
A very long thin wire carries a current I1 is next to a square
wire loop of width L = 5 .0 cm. Both the wire and the loop lay in
the same plane with a gap of s = 1 .0 cm between them. The square
loop has a break where two parallel plates with surface area A = 4
.0 cm 2 are separated by a gap of d = 1 µm. The radius of the wire
