Question: What Is The Formula To Find The Force On A Rectangular Current Carrying Coil?

What factors affect magnetic force in current carrying coil?

Factors Affecting the Strength of the Magnetic Field of an Electromagnet: Factors that affect the strength of electromagnets are the nature of the core material, strength of the current passing through the core, the number of turns of wire on the core and the shape and size of the core..

What is the vector expression for the magnetic force on a current carrying conductor?

The magnetic force on a current-carrying wire in a magnetic field is given by →F=I→l×→B. For part a, since the current and magnetic field are perpendicular in this problem, we can simplify the formula to give us the magnitude and find the direction through the RHR-1. The angle θ is 90 degrees, which means sinθ=1.

What is the strength of the magnetic field of a coil which is carrying current dependent on?

The strength of magnetic field produced by a current carrying solenoid is: Directly proportional to the number of turns in the solenoid. Directly proportional to the strength of current in the solenoid. Dependent on the nature of “core material” used in making the solenoid.

What does B in physics mean?

B = magnetic flux density. b = beta particle. B = bell (sound intensity) Bq = becquerel (activity) c.

What happens when rectangular current carrying coil is placed in magnetic field?

As the current carrying conductor experiences a force when placed in a magnetic field, each side of a current carrying rectangular coil experiences a force in a magnetic field. … the direction of force is perpendicular to the plane containing PQ and B. It is directed outward direction as shown in figure.

What is the magnetic field formula?

A current-carrying wire feels a force in the presence of an external magnetic field. It is found to be F=Bilsinθ F = Bi l sin θ , where ℓ is the length of the wire, i is the current, and θ is the angle between the current direction and the magnetic field.

What does Lenz law state?

Because like magnetic poles repel each other, Lenz’s law states that when the north pole of the bar magnet is approaching the coil, the induced current flows in such a way as to make the side of the coil nearest the pole of the bar magnet itself a north pole to oppose the approaching bar magnet.

What is the relationship between force and current?

Current is directly proportional to magnetic force for a straight current carrying conductor in a uniform magnetic field. So the force is directly proportional to the size of the current. Practically this means the following: If the current is doubled the force on the conductor will double.

How does current affect electromagnetic strength?

When the electric current moves through a wire, it makes a magnetic field. … The strength of an electromagnet can be increased by increasing the number of loops of wire around the iron core and by increasing the current or voltage.

What does Faraday’s law mean?

Faraday’s law of induction (briefly, Faraday’s law) is a basic law of electromagnetism predicting how a magnetic field will interact with an electric circuit to produce an electromotive force (EMF)—a phenomenon known as electromagnetic induction.

What does F BIL stand for?

F = BIL (f=force, b=magnetic field, i=current, l=length of conductor)

How do you calculate the force of a wire?

The equation for calculating the force on a wire is Force (N) = magnetic flux density (T) × current (A) × length (m) or, in short F = B I L.

What is the right hand rule in physics?

The right hand rule states that, to find the direction of the magnetic force on a positive moving charge, the thumb of the right hand point in the direction of v, the fingers in the direction of B, and the force (F) is directed perpendicular to the right hand palm.

What is meant by Fleming’s left hand rule?

: a rule in electricity: if the thumb and first two fingers of the left hand are arranged at right angles to each other on a conductor and the hand oriented so that the first finger points in the direction of the magnetic field and the middle finger in the direction of the electric current then the thumb will point in …

What is the formula for Lorentz force?

Lorentz force, the force exerted on a charged particle q moving with velocity v through an electric field E and magnetic field B. The entire electromagnetic force F on the charged particle is called the Lorentz force (after the Dutch physicist Hendrik A. Lorentz) and is given by F = qE + qv × B.
