Effect of Bending on Magnetic Moment
When an iron bar with a magnetic moment M is bent at the middle, the magnetic moment of the new magnet can be calculated using the concept of vector addition.
Vector Addition of Magnetic Moments
- The magnetic moment of the original iron bar can be represented as M = I * A, where I is the current flowing in the bar and A is the area enclosed by the current loop.
- When the bar is bent at the middle, the two halves of the bar will have magnetic moments in the same direction but at an angle of 60 degrees with each other.
- The resultant magnetic moment of the bent bar can be calculated using the formula M' = M * cos(60), where M' is the magnetic moment of the bent bar.
Calculating the New Magnetic Moment
- Given that the two halves of the bent bar make an angle of 60 degrees with each other, the new magnetic moment M' can be calculated as M' = M * cos(60).
- Since cos(60) = 0.5, the new magnetic moment M' = 0.5 * M.
- Therefore, the magnetic moment of the bent iron bar is half of the original magnetic moment M.
By bending the iron bar at the middle, the magnetic moment of the new magnet is reduced to half of the original magnetic moment. This change in magnetic moment is due to the alteration in the orientation of the magnetic domains within the iron bar.
