What is the relationship between radius and magnetic field?

r=mvqB r = m v q B . Here, r is the radius of curvature of the path of a charged particle with mass m and charge q, moving at a speed v perpendicular to a magnetic field of strength B. If the velocity is not perpendicular to the magnetic field, then v is the component of the velocity perpendicular to the field.

What is the relationship between the magnetic force and the length of a conductor with current in the magnetic field?

For a wire exposed to a magnetic field,F=IlBsinθ F = IlB sin ⁡ describes the relationship between magnetic force (F), current (I), length of wire (l), magnetic field (B), and angle between field and wire (θ). The direction of the magnetic force can be determined using the right hand rule, as in fig [[17951]].

Does the radius of a solenoid affect the magnetic field?

The magnetic field inside a solenoid is proportional to both the applied current and the number of turns per unit length. There is no dependence on the diameter of the solenoid, and the field strength doesn’t depend on the position inside the solenoid, i.e., the field inside is constant.

What is the relation between magnetic field and number of turns of the conducting wire?

Lines of Force around an Electromagnet The magnetic field strength of an electromagnet is therefore determined by the ampere turns of the coil with the more turns of wire in the coil the greater will be the strength of the magnetic field.

What is the relation between magnetic field and potential difference?

The presence of a magnetic field merely increases or decreases this potential difference once the particle has moved, and it is this change in the potential difference that we wish to determine.

What is the relation between momentum and magnetic field?

The answer is that if you have a magnetic field and some charges, there will be some angular momentum in the field. It must have been put there when the field was built up. When the field is turned off, the angular momentum is given back.

What is the relationship between force and length of conductor?

The experiments above lead to the conclusion that the force F on the conductor is proportional to the length of wire in the field, L , the current I and the strength of the field, represented by the flux density B . (There is also an angle factor to consider, but we will leave this aside for now.)

What is the relationship between current flow and magnetic fields?

Electricity and magnetism are closely related. Flowing electrons produce a magnetic field, and spinning magnets cause an electric current to flow. Electromagnetism is the interaction of these two important forces.

When the radius of solenoid decreases the magnetic field strength inside the solenoid?

The strength of the magnetic field of solenoid increases with the decrease in number of turns in the solenoid.

What happens to the magnetic field in the solenoid when the length of the solenoid increases?

Explanation: The magnetic field of a solenoid is inversely proportional to the length. Hence as the length increases, the magnetic field decreases.

What is the relationship between magnetic field strength and position?

As it is covered by Biot– Savart law, the magnetic field strength is inversely proportional to the distance from the current carrying conductor. In this application- note we will be using the same concept in the position-sensing application.

How does radius affect potential difference?

Right! Since E is a vector, and the distance and charges on both sides are equal, then they always simply cancel out to zero. Whereas with electric potential, a scalar quantity, it is not affected by direction, merely magnitude, in which case both are positive, so the radius change will definitely affect it.

How does the radius of the solenoid affect the magnetic field?

The radius of the solenoid doesn’t contribute to the magnetic field inside of the solenoid. The only variables whoch determine the strength of the magnetic field are the number of turns per unit length and the current magnitude.

What is a solenoid and how does it work?

A solenoid is a long coil of wire wrapped in many turns. When a current passes through it, it creates a nearly uniform magnetic field inside. Solenoids can convert electric current to mechanical action, and so are very commonly used as switches.

What is the relationship between magnetic field inside and outside conductor?

Inside the conductor the magnetic field B increases linearly with r. Outside the conductor the magnetic field becomes that of a straight conductorand decreases with radius. Note that the expressions for inside and outside would approach the same value at the surface if the magnetic permeabilitywere the same.

How do you increase the number of turns on a solenoid?

To fit more turns on a solenoid coil, requires a larger coil or smaller wire. The radius of the solenoid doesn’t contribute to the magnetic field inside of the solenoid. The only variables whoch determine the strength of the magnetic field are the number of turns per unit length and the current magnitude.
