Web29 jul. 2024 · Assertion(A) : The strength of the magnetic field produced at the centre of a current carrying circular coil increases on increasing the radius of the circular coil. … WebThe total number of magnetic field lines penetrating through a defined surface in a specific amount of time is called the magnetic flux. It is directly proportional to the number of magnetic field lines that pass through the surface. The more concentrated the lines, the greater the flux density.

Web1 Answer. Sorted by: 5. Because there are no magnetic charges the simplest system that can generate a magnetic field is a dipole. The field from a dipole (magnetic or electric) falls off as 1 / r 3 rather than 1 / r 2 so the field strength falls off more rapidly with distance than the electric field from a point charge. WebMagnetic Field Strength Magnetic field strength is directly proportional to the amount of current in the conductor (and also directly proportional to the number of “turns” in a coiled wire), such that the unit of measurement for magnetic field strength is …

So this just means the field will also vary with time, but still be proportional to the current at any instant in time. – BioPhysicist. Aug 20, 2024 at 0:53. @AaronStevens Perhaps my wording was off.
