what determines the strength of a magnetic field?

Answer 1

the amount of space between the magnet and another magnet the same size it takes to attract them both together! Just look at it on a search engine like yahoo, or maybe google.

Answer 2

the challenge isn’t too hard. could be simplified. On a droop, verify this: 6.3^2 + 12^2 = 13.6^2. Yahoo! Left hand area balances superb hand area! The triangle with facets 6.3 cm, 12 cm and 13.6 cm is reliable-angled. Makes issues less difficult. Draw a triangle XYZ with XY = 6.3 cm, YZ = 12 cm and XZ = 13.6 cm (the hypotenuse) --- on a sheet of paper. word that XY and YZ has an excellent perspective between them. Circle X and Y. it quite is the place there are 2 currents of length 15.0 A getting into the internet site oftentimes. The magnetic container located at factor placed at a distance R removed from an prolonged at once present day I is given via B = (mu-nought)*(I) / (2*pi*R) “mu-nought” is (4*pi*10^-7), so B = (2I)/R the two currents make magnetic fields B1 and B2 at Z, so as that they are at superb angles with XZ and YZ respectively. the perspective between B1 and B2 is theta, the place theta is likewise the perspective at Z in triangle XYZ. Theta is genuinely chanced on because of fact all 3 facets of XYZ are properly-known, using basic sin, tan or cos. Draw a parallelogram with 2 arrows for facets, of length B1 and B2, with the perspective theta between them. discover the diagonal of the parallelogram between B1 and B2, and the perspective it makes with B1. for this reason you understand it quite is the size and path of the consequent container. ok, right here is the place physics ends, something is arithmetic. It’s as much as you presently to the two draw to scale or calculate.

Answer 3

its stored power
