- Magnetic fields do not require a medium to propagate, unlike mechanical waves.
- The direction of the magnetic field lines represent the direction a north magnetic pole would move if placed in the field.
- Magnetic fields can only be produced by moving charges or currents, and not by stationary charges.
- Magnetic fields exert forces on moving charges according to the Lorentz force law.
What else can I help you with?
How do you calculate magnetic fields strength given current and distance away from the wire?
To calculate magnetic field strength near a current-carrying wire, you can use the formula B = (μ₀ * I) / (2 * π * r), where B is the magnetic field strength, μ₀ is the magnetic constant (4π x 10^-7 T*m/A), I is the current in the wire, and r is the distance from the wire. Simply plug in the values and solve for B.
What are applications of B-H curve?
The B-H curve is used in the design of electromagnetic devices such as transformers, inductors, and electric motors to understand the magnetic properties of materials. It helps in determining the magnetic permeability, hysteresis losses, and saturation characteristics of magnetic materials used in electrical engineering applications. The B-H curve also plays a role in calibrating magnetic sensors and investigating material behavior under varying magnetic fields.
What are the units of flux and how are they calculated in the context of electromagnetic fields?
The units of flux in the context of electromagnetic fields are measured in Weber (Wb) or Tesla meters squared (Tm). Flux is calculated by multiplying the magnetic field strength (B) by the area (A) perpendicular to the field. The formula for calculating flux is B A.
Uniform And Non-Uniform Magnetic field And Calculation of its strength?
The answer depends on the source of the magnetic field. For instance, the magnetic field due to a current carrying wire is given by the formula mu*I/(2*pi*r). Magnetic fields follow the principle super position so they can be added up no problem.
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.
If A is true then B must be true.?
Not necessarily. It will all depend on the statements A and B.
What are unconditional statements in c plus plus?
Unconditional statements are statements that are invoked unconditionally. Conditional statements have a controlling expression, while unconditional statements do not. For example: void f (bool b) { if (b==true) do_something(); // conditional statement (controlled by the expression b==true) do_something_else(); // unconditional (executes regardless of b's value) }
If there is a correlation b Event A and Event B statements is true?
event B has something in common with event A
If there is a correlation between event a and Event B what statements is true?
event B has something in common with event A
If there is a correlation between event A and event B statements is true?
event B has something in common with event A
What has the author B Coppi written?
B. Coppi has written: 'Magnetic energy conversion processes and solar flares' -- subject(s): Plasma turbulence, Solar flares, Solar magnetic fields
What has the author A B Rechester written?
A. B Rechester has written: 'Calculation of the Kolmogorov entropy for motion along a stochastic magnetic field' -- subject(s): Mathematical models, Stochastic processes, Magnetic fields, Entropy
What is circular logic?
Circular logic would be a statement or series of statements that are true because of another statement, which is true because of the first. For example, statement A is true because statement B is true. Statement B is true because statement A is true
What does symbol B mean in physics?
In physics, symbol B is often used to represent magnetic field. Magnetic fields are vector quantities that exert a force on moving electric charges and magnetic materials. This symbol is commonly used in equations involving electromagnetic phenomena.
Which of these statements about animal communication are true a. Communication helps animals to find mates b. Communication helps animals find their food c. Communication helps animals?
All of those statements are true. There is no exception.
Which of the following statements are true about the line y mx b?
If you mean straight line equation: y = mx+b then m is the slope and b is the y intercept
What does always true mean in math terms?
In mathematical terms, "always true" refers to statements or equations that hold valid under all circumstances or for all values in their domain. For example, the equation ( a + b = b + a ) (the commutative property of addition) is always true, as it applies to any real numbers ( a ) and ( b ). Such statements are considered universally valid and do not depend on specific conditions or exceptions.
