How to find the direction of magnetic force in a given scenario?
To find the direction of magnetic force in a given scenario, use the right-hand rule. Point your right thumb in the direction of the current, and curl your fingers in the direction of the magnetic field. The direction your fingers point is the direction of the magnetic force.
What is the significance of determining the magnetic field direction in a given scenario?
Determining the magnetic field direction is important because it helps understand how magnetic forces will act on objects in that scenario. This information is crucial for designing and operating devices like motors, generators, and compasses.
What do magnetic field line show?
Magnetic field lines show the direction in which a magnetic north pole would be attracted. They provide a visual representation of the strength and direction of the magnetic field in a given space.
What are the dimensions of magnetic field?
The dimensions of magnetic field are given in units of Tesla (T), which is equivalent to kg/s^2A. Magnetic field is a vector quantity with both magnitude and direction.
What is the rate of change of the magnetic field with respect to time (db/dt) in a given scenario?
The rate of change of the magnetic field with respect to time (db/dt) measures how quickly the magnetic field is changing over time in a specific situation.

A current in a long straight wire produces a magnetic field. These magnetic field lines?
form concentric circles around the wire, with the direction given by the right-hand rule (curl your fingers in the direction of the current, and your thumb points in the direction of the magnetic field). The strength of the magnetic field decreases as you move further away from the wire.
What do we call the lines of force surrounding a magnet?
Magnetic field lines. These lines represent the direction in which a small north magnetic pole would tend to move if placed at any given point in the field.
What conditions are necessary for magnetic field to produce a force on a wire?
A current has to flow in the circuit to induce a force on the circuit
What is net magnetic field?
The net magnetic field refers to the combined magnetic field resulting from the contribution of multiple magnetic sources in a given space. It is calculated by summing up the magnetic fields generated by individual sources or components present in the region. The net magnetic field's strength and direction can vary depending on the orientation and magnitude of the contributing magnetic fields.
Does a magnetic field exert any pressure on a charge moving perpendicular to its direction?
Only moving charges experience force in a magnetic field. i.e.,on moving ,a charge q,with velocity v ,experiences a force in the presence of electric field(E) and magnetic field (B). It can be represented as F= q(v x B)~(Ftotal=Felectricfield + Fmagneticfield ) Force acts perpendicular to both magnetic field and velocity of the electron. Its direction is given by right hand thumb rule or screw rule. The magnetic force is zero if charge is not moving, since lvl=0.
Why is magnetic induction a vector quantity?
Magnetic field induction at a point is defined as the FORCE experienced by a unit north pole placed at that point. Since force is a vector quantity, manetic field induction also becomes a vector quantitiy.
Definition of uniform-magnetic field?
A uniform magnetic field is a magnetic field that has the same strength and direction at all points in a given region of space. It has constant magnetic flux density and does not vary in magnitude or direction within the specified area. Uniform magnetic fields are often used in scientific experiments and applications to provide consistent and predictable conditions for studying magnetic effects.
