Given Data:
- Length of the metallic rod (l) = 1 m
- Angular frequency (ω) = 400 rad/s
- Magnetic field (B) = 0.5 T
Calculating the induced emf:
1. Calculating the magnetic flux through the rod:
- The magnetic field is parallel to the axis of rotation, so the magnetic flux through the rod is given by φ = B*l^2
- Substituting the given values, we get φ = 0.5 * 1^2 = 0.5 Wb
2. Calculating the emf induced:
- The emf induced in a rotating rod is given by ε = -ω * φ
- Substituting the values, we get ε = -400 * 0.5 = -200 V
3. Direction of the induced emf:
- The direction of the induced emf is given by Lenz's Law, which states that the induced emf will be in a direction that opposes the change in magnetic flux.
- In this case, the emf will be induced in such a way that it creates a current that produces a magnetic field opposite to the external magnetic field.
4. Emf induced between the center and the ring:
- The emf induced between the center and the ring can be calculated by considering the distance between the center and the ring.
- As the rod rotates, the emf induced will vary along the length of the rod, with the maximum emf induced at the ends and zero emf at the center.
Therefore, the emf induced between the center and the ring will be maximum at the ring end and decrease linearly towards the center.
- Length of the metallic rod (l) = 1 m
- Angular frequency (ω) = 400 rad/s
- Magnetic field (B) = 0.5 T
Calculating the induced emf:
1. Calculating the magnetic flux through the rod:
- The magnetic field is parallel to the axis of rotation, so the magnetic flux through the rod is given by φ = B*l^2

- The emf induced between the center and the ring can be calculated by considering the distance between the center and the ring.
- As the rod rotates, the emf induced will vary along the length of the rod, with the maximum emf induced at the ends and zero emf at the center.
Therefore, the emf induced between the center and the ring will be maximum at the ring end and decrease linearly towards the center.
