What happens when two magnetic fields are perpendicular?

At any given point, if the fields are in the SAME direction the sum will be stronger and in the same direction. If the fields are in opposite directions the sum will be weaker and will be in the direction of the stronger field.

What happens when two magnetic fields are pointing in the same direction?

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.

How do you determine the direction of induced electric field?

1. The direction of the induced e.m.f. is determined by :
2. The current is flowing in two coaxial coils in the same direction.
3. A triangular loop is placed in a dot ⨀ magnetic field as shown in figure.
4. The long straight wire in figure (a) carries a constant current i.

Why is magnetic field perpendicular?

The superficial answer is simply that the Lorentz (magnetic) force is proportional to v×B, where v is the particle velocity and B is the magnetic field. Since the vector cross product is always at right angles to each of the vector factors, the force is perpendicular to v.

What happens when electric field is perpendicular to magnetic field?

Perpendicular electric and magnetic field creates light or other electromagnetic waves.

What will happen if two parallel wires are placed close together and have identical currents flowing through them in the same direction?

Thus, when two parallel wires carry current in the same direction, they exert equal and opposite attractive forces on each other. There will be no force, since the currents cancel. There will be an attractive force between the wires. There will be a repulsive force between the wires.

Can two magnetic field cancel each other?

Magnetic fields can cancel each other out. This is owed to the factor that magnetic fields are vector quantities. If the magnitude of two fields is equal, but the pull is in opposite directions, the net result is that the magnetic fields will cancel out.

Is induced electric field conservative or non conservative Why?

Specifically, the induced electric field is nonconservative because it does net work in moving a charge over a closed path, whereas the electrostatic field is conservative and does no net work over a closed path.

How do you find the induced electric field due to changing the magnetic field?

E=ϵ2πr. When the magnetic flux through a circuit changes, a nonconservative electric field is induced, which drives current through the circuit.

What is the direction of magnetic field in a bar magnet?

Bar Magnet By convention, the field direction is taken to be outward from the North pole and in to the South pole of the magnet. Permanent magnets can be made from ferromagnetic materials. As can be visualized with the magnetic field lines, the magnetic field is strongest inside the magnetic material.

How do you determine the direction of a magnetic field in a solenoid?

To do this, point your right thumb in the direction that the current travels in the coiled wire in the solenoid and curl your fingers. * The direction your fingers point will determine the direction of the magnetic field created by the current. Alternately the right-hand-grip rule is easier to use with solenoids.

How do magnetic and electric fields interact with each other?

When charges are stationary, their electric fields do not affect magnets. But, when charges move, they produce magnetic fields that exert forces on other magnets. When there is relative motion, a connection between electric and magnetic fields emerges—each affects the other. Example 1.

How does a magnet induce a current?

– Ampere / Faraday / Henry moving a magnet near a conducting loop can induce a current. – The magnetic forces between two bodies are due to the interaction between moving electrons in the atoms. – Inside a magnetized body (permanent magnet) there is a coordinated motion of certain atomic electrons .

How to magnetize a sphere of linear magnetic material?

A sphere of linear magnetic material is placed in an originally uniform magnetic field magnetic field B 0 . Find the new field inside the sphere. Solution: The external magnetic field will magnetize the sphere.

What is the direction of the earth’s magnetic field on its surface?

The Earth’s magnetic field on its surface is only about 5 × 10 −5 T, or 0.5 G. The direction of the magnetic force F is perpendicular to the plane formed by v and B, as determined by the right hand rule 1 (or RHR-1 ), which is illustrated in Figure 1. RHR-1 states that, to determine the direction of the magnetic force on…
