Why is B the symbol for magnetic induction?
When the magnetic field is observed from the North pole, the magnetic field emerges and and goes towards south. However, inside a magnet there is no field at all, thus forming butterfly shape lines. Hence, B stands for butterfly and due to this concept, scientists used the symbol B for magnetic induction.
What are two fields surround a moving electric charge?
A moving electric charge will produce a magnetic field.A moving electric charge will produce a magnetic field.A moving electric charge will produce a magnetic field.A moving electric charge will produce a magnetic field.
What are materials attracted by a magnet called?
It is called the magnetic force. This is a force caused by the attraction or repulsion of the magnetic fields of the materials.

Why force exerted by a magnetic field on stationary elctric dipole is zero?
The force on a charge by a magnetic field is given by F = Bq v sin@ v - the speed of the charged particle with charge q. B - magnetic field induction in tesla. @ is the angle between the velocity vector and magnetic field vector. As dipole is stationary, the speed of charges is zero. So the force = 0 Hence the result.
What Greek letter is used to symbolize the magnetic field?
The Greek letter "B" (beta) is commonly used to symbolize the magnetic field in physics.
Why magnetic field is represented by b?
The notation "B" is used to represent magnetic field because it was traditionally chosen by physicists to honor the scientist Carl Friedrich Gauss, who made significant contributions to the understanding of magnetism. It is simply a convention in the field of physics to use "B" for magnetic field.
What is the formula for a uniform magnetic field?
The formula for a uniform magnetic field is B I / (2 r), where B is the magnetic field strength, is the permeability of free space, I is the current, and r is the distance from the current.
Choose the best description of a magnetic field line A Magnetic field lines for a bar magnet are parallel to the magnet B A magnetic field line shows the direction a compass needle would?
B. A magnetic field line shows the direction a compass needle would align in a magnetic field.
What is the potential energy of a point magnetic dipole of moment M placed in a uniform magnetic field B?
The potential energy of a magnetic dipole in a magnetic field is given by U = -M · B, where M is the magnetic moment and B is the magnetic field. The negative sign indicates that the potential energy decreases as the dipole aligns with the field.
How to calculate the magnetic field strength around a current-carrying wire?
To calculate the magnetic field strength around a current-carrying wire, you can use the formula B ( I) / (2 r), where B is the magnetic field strength, is the permeability of free space, I is the current in the wire, and r is the distance from the wire.
What is the formula for magnetic flux and how is it calculated?
The formula for magnetic flux is B A cos(), where is the magnetic flux, B is the magnetic field strength, A is the area of the surface, and is the angle between the magnetic field and the surface normal. Magnetic flux is calculated by multiplying the magnetic field strength, the area of the surface, and the cosine of the angle between the magnetic field and the surface normal.
What is meant by tangent in physics?
when a magnetic substance in placed i two uniform magnetic field (b) and (h) which are mutually perpendicular and coplanar to each other. then the magnetic field intensity of magnetic field of b which making angle θ with h is tanθtimes of h.mathamatically B=tanθxH.
What is B in physics?
In physics, B typically refers to the magnetic field. Magnetic field B represents the strength and direction of the magnetic force acting on a moving charged particle or current-carrying wire. It is measured in tesla (T) or gauss (G) units.
How is the torque on a loop of current in a magnetic field determined when considering the interactions between the magnetic field and the current loop?
The torque on a loop of current in a magnetic field is determined by the interactions between the magnetic field and the current loop. This torque is calculated using the formula x B, where is the torque, is the magnetic moment of the loop, and B is the magnetic field strength. The direction of the torque is perpendicular to both the magnetic moment and the magnetic field.
If the strength of the magnetic field at B is 6 units the strength of the magnetic field at A is?
Since the magnetic field strength decreases with distance from the source (B), the strength of the magnetic field at point A would be less than 6 units. Without additional information, we cannot determine the precise value of the magnetic field strength at point A.
How do you find acceleration due to magnetic field?
To find acceleration due to a magnetic field acting on a charged particle, you can use the equation ( F = qvB ), where ( F ) is the magnetic force, ( q ) is the charge of the particle, ( v ) is the velocity of the particle, and ( B ) is the magnetic field strength. Once you have calculated the magnetic force, you can use Newton's second law (( F = ma )) to find the acceleration (( a )) of the particle.
