So if you have two current-carrying, parallel wires with magnetic fields circling around them in the same direction, they will attract each other, as shown in the tutorial; at the point at which their respective magnetic fields intersect, they are traveling in opposite directions, and opposites attract.

The wires are at right angles, so there is no force at the point of closest approach because the magnetic field from one wire is parallel to the other wire.

Yes. Two wires repel each other when carrying current in opposite directions—the force on each wire is equal in magnitude and opposite in direction. correct Perpendicular wires exert no net force on one another, but there will be a torque. — There will be no net force on the wires, but there will be a torque.

If a straight conducting wire is placed in a plane perpendicular to a uniform magnetic field, and is moving in a direction perpendicular to the field, then each charge q in the wire experiences a magnetic force of magnitude F = qvB. The negatively charged electrons will accelerate in response to this force.

Any current-carrying wire creates a magnetic field around itself and this magnetic field can exert a force on another wire with another current. The force due to the magnetic field is perpendicular to both magnetic field and the current direction and is proportional to both current and magnetic field.

The direction is obtained from the right hand rule. Note that two wires carrying current in the same direction attract each other, and they repel if the currents are opposite in direction.

Answer. Figure 22.2. 1: Two parallel current-carrying wires will exert an attractive force on each other, if their currents are in the same direction. which does indeed have the same magnitude as the force exerted on the second wire.

Since both wires have currents flowing in the same direction, the direction of the force is toward each other. Whether the fields are identical or not, the forces that the wires exert on each other are always equal in magnitude and opposite in direction (Newton’s third law).

If the current-carrying wire is placed in a magnetic field (whose lines of force are at right angles to the wire) then it will experience a force at right angles to both the current direction and the magnetic field lines. The force increases if the strength of the magnetic field and/or current increases.

The middle wire can’t be attracted or repulsed by both wires simultaneously, if one is attractive, the other is repulsive.

The fingers of your right hand will wrap around the wire in the same direction as the magnetic field. When the currents flow in the same direction the magnetic field will be opposite and the wires will attract.

The direction of magnetic field on the conductor is determined by Fleming’s right hand rule. Thus, gives us that the direction of magnetic field turns out to be opposite to each other. This results in repulsion of the conductors carrying current in opposite directions relatively and vice versa.

Parallel wires with current flowing in the same direction, attract each other. Parallel wires with current flowing in the opposite direction, repel each other.

Two parallel wires carrying currents in the same direction attract each other due to magnetic interaction between two wires carrying currents because the current in a wire produces a magnetic field and the magnetic interaction is of attractive nature when current in the two parallel wires is in the same direction.

Summary. The magnetic field strength at the center of a circular loop is given by B=μ0I2R(at center of loop), where R is the radius of the loop. RHR-2 gives the direction of the field about the loop.

Summary. The magnetic field strength at the center of a circular loop is given by B=μ0I2R(at center of loop), where R is the radius of the loop.

Hence the magnetic field at the center of the circular coil is B=μ0i2r.

The right hand rule states that: to determine the direction of the magnetic force on a positive moving charge, point your right thumb in the direction of the velocity (v), your index finger in the direction of the magnetic field (B), and your middle finger will point in the direction of the the resulting magnetic force …

Fleming’s left-hand rule is used for electric motors, while Fleming’s right-hand rule is used for electric generators. Since neither the direction of motion nor the direction of the magnetic field (inside the motor/generator) has changed, the direction of the electric current in the motor/generator has reversed.
