EXAMPLE 3.4 Calculate the magnetic flux coming out from the surface containing magnetic dipole (say, a bar magnet) as shown in figure. Solution Magnetic dipole is kept, the total flux emanating from the closed surface S is zero. So, WebThe magnetic field due to a short magnet at a point on its axis at a distance X cm from the middle point of the magnet is 200 Gauss. The magnetic field at a point on the neutral axis at a distance of X cm from the middle of the magnet is: 1. 100 Gauss. 2. 400 Gauss. 3. 50 Gauss. 4. 200 Gauss pima county news
