Magnetic field vs distance equation
WebFeb 13, 2015 · Then the magnetic field along the axis will be proportional to $(\cos \theta_1 - \cos \theta_2)$. If you're not along the axis, then abandon all hope. I'm not sure that a closed-form solution even exists; you might be able to write something down in terms of elliptic functions (or integrals thereof), but it's going to be pretty nasty. WebBut the magnetic field of the Earth is relatively weak. It is strong enough to change the direction of charged particle coming from the Sun and outer space but i think the force due to another big magnet would be fairly small. Also, consider that the Sun also has magnet fields which are fairly strong. Any thoughts?? ( 3 votes) Show more comments

WebThe dimensions of electric field are newtons/coulomb, \text {N/C} N/C. We can express the electric force in terms of electric field, \vec F = q\vec E F = qE. For a positive q q, the electric field vector points in the same … WebThe induced electric field in the coil is constant in magnitude over the cylindrical surface, similar to how Ampere’s law problems with cylinders are solved. Since E → is tangent to the coil, ∮ E → · d l → = ∮ E d l = 2 π r E. When combined with Equation 13.12, this gives. E …
WebThe temperature dependences of the magnetic moment M(T) were measured upon cooling at T = 2–300 K in a static magnetic field H = 5000 Oe. The cooling rate was 2 K/min. The field dependencies of the magnetic moment M(H) were obtained at temperatures 2, 4, 6, 8, and 10 K in the field range of 0–90,000 Oe. The field change rate was 5000 Oe/min.
