Answer:
The magnitude of the voltage is
and the direction of the current is clockwise.
Explanation:
Given that,
Number of turns = 9
Magnetic field = 0.5 T
Diameter = 3 cm
Time t = 0.14 s
We need to calculate the flux
Using formula of flux

Put the value into the formula


We need to calculate the emf
Using formula of emf




Negative sign shows the direction of current.
Hence, The magnitude of the voltage is
and the direction of the current is clockwise.
The high voltage generators which are used in X-Ray imaging system are magnetic devices. There are various magnetic X-rays imaging techniques.
X-rays are a form of electromagnetic radiations. X-ray imaging creates picture of the inside of your body. Polarized x-rays have emerged as unique probed due to their specific interaction with magnetic materials.Magnetic resonance imaging deals with
static and varying magnetic fields.
Explanation:
If the two charges are point charges - i.e., they don't have a size - the force between these charges depends on the
• Magnitude if each charge, q1 and q2
• Sign of each charge (+ or -)
• Distance between the charges, r
This is essentially Coulomb’s Law:
FE = (kq1q2)/r2
For collections of charges, you need to find the electric field E, and then use this fields to find a force on a small test charge q in the field. The test charge is always small to help you map the electric field, but not disturb it.
Answer:
The allowed current in the cable is 1.15 A.
Explanation:
Given that,
Distance = 1.00 m
Suppose the magnetic field is
and if the experiment is to be accurate to 1.0 %
We need to calculate the current
Using formula of magnetic field


Put the value into the formula


If the experiment is to be accurate to 1.0%
Then,
We need to calculate the allowed current in the cable



Hence, The allowed current in the cable is 1.15 A.
