Answer:
Current can be induced in a lot of ways. I'll try and list as much of these methods as I can here.
1. Moving a bar magnet relative to a wire coil
2. Moving a wire coil relative to a magnet.
3. Move a wire coil that has electricity flowing though it relative to a wire coil without electricity flowing through it.
4. Moving a current carrying circuit relative to a non-current carrying circuit
5. Rapidly opening and closing the switch of a current carrying circuit beside a non current carrying circuit.
6. Moving a bar magnet through the middle of a wire coil.
7. Moving a wire coil through a magnet
8. Moving a circuit relative to a magnetic field.
The main idea is to cause a change in the magnetic field, or to change the available area of the wire loop, or to change the angle between the field and the loop.
Answer:
I dont get what your asking sorry boo
Explanation:
The correct answer is letter C, regular reflection.
<span>An image seen in a smooth dinner plate is an example of a
regular reflection. This phenomenon only occurs in smooth and polished surfaces.
During this stage light occurs at a certain angle and is reflected back at the
same angle producing reflections in a way like a mirror does this commonly.</span>
Answer:
1.507×10⁻⁴ T
Explanation:
a = 5 cm = 0.05 m
b = 7 cm = 0.07 m
j = 1 A/cm²
Distance from magnetic field = d = 10 cm = 0.1 m
μ₀ = Vacuum permeability = 4π×10⁻⁷ H/m
Magnetic of hollow cylinder
∴ Magnitude of the magnetic field at a distance d = 10 cm from the axis of the cylinder is 1.507×10⁻⁴ T
