A small section of electrified wire is 1 in length and 5A in current intensity. If it is placed at a certain point in the magnetic field and the magnetic field force is 0.1N, then the magnetic induction intensity at that point must be? To explain in detail, the answer is that B is greater than or equal to 2T. I think it should be less than or equal to 2T. Why?

It's estimated to be 1cm, and then the maximum value is 0.1N in the case of two vertical, the formula F = IBL, but in some cases, if it's not vertical, then its effective length is less than 1cm, that is, l becomes smaller, so B should become larger at this time,

Magnetic induction intensity: when a small section of electrified straight wire is placed perpendicular to the magnetic field, the magnetic field force F is proportional to the current intensity I____ ,
It is proportional to the length L of the conductor______ Where f / IL is related to the length and current intensity of the electrified wire______ It reflects the change of the magnetic field______ F / IL is defined as the___________ The unit is_______ The direction is the direction of the magnetic induction line at this point_________ It is also the position of the N-pole when the small needle is stationary there_______ .

There is a downward current in a straight wire placed vertically. Somewhere in the east of the wire, the direction of the magnetic field of the wire is

It points due south
Right hand rule: clench the fist with the right hand, point the thumb to the current direction, and the direction pointed by the other four fingers is the magnetic line direction

In a uniform magnetic field, there is an electrified wire with a length of 0.4m, and the current in the wire is 20A
When the wire is perpendicular to the magnetic field, the magnetic force is 0.015n

F=B I L
The direct band formula B is the magnetic field intensity I is the current intensity L is the length of the conductor, all three of them are vertical
Universal formula
You want B to be B = f / IL
I think it's very simple
