Magnetic Field Strength?

Question

Why will the magnetic field strength be further increased inside a current carrying coil if a piece of iron is also in the coil?

Answer 1

Because the dipoles in a ferromagnetic material (like iron) tend to line up with an applied magnetic field so that they enhance the field from the wires.

Answer 2

An electromagnet is an object that acts like a magnet, but its magnetic force is created and controlled by electricity--thus the name electromagnet. By wrapping insulated wire around a piece of iron and then running electrical current through the wire, the iron becomes magnetized. This happens because a magnetic field is created around a wire when it has electrical current running through it. Creating a coil of wire concentrates the field. Wrapping the wire around an iron core greatly increases the strength of the magnetic field.

Answer 3

You are putting in a piece of magnetic material in the coil and it's magnetic domains will alight with the field increasing the strength.

Answer 4

the problem isn’t too stressful. would nicely be simplified. On a slump, verify this: 6.3^2 + 12^2 = 13.6^2. Yahoo! Left hand area balances suited hand area! The triangle with sides 6.3 cm, 12 cm and 13.6 cm is sweet-angled. Makes issues easier. 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 a suited attitude between them. Circle X and Y. it is the place there are 2 currents of length 15.0 A entering the website many times. The magnetic container located at factor located at a distance R removed from an prolonged at once contemporary I is given by ability of 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 suited angles with XZ and YZ respectively. the attitude between B1 and B2 is theta, the place theta is likewise the attitude at Z in triangle XYZ. Theta is actual got here upon via fact all 3 sides of XYZ are time-honored, employing basic sin, tan or cos. Draw a parallelogram with 2 arrows for sides, of length B1 and B2, with the attitude theta between them. locate the diagonal of the parallelogram between B1 and B2, and the attitude it makes with B1. subsequently you know it is the size and direction of the consequent container. ok, right this is the place physics ends, something is arithmetic. It’s as much as you presently to the two draw to scale or calculate.
