Magnetic Field vs Electric Field - Physics Forums
2013年3月4日 · What you call electric and magnetic field depends on your reference frame, and it is rather a splitting in electric and magnetic components of this field (like you split your space-time vector wrt. to a reference frame in one temporal and three spatial components).The magnetic and electric fields are working in opposition to each other.
Measuring electric field vs magnetic field - Physics Forums
2023年11月8日 · What is the primary difference between measuring an electric field and a magnetic field? The primary difference lies in the nature of the fields and the instruments used. Electric fields are measured in volts per meter (V/m) using devices like electrometers or field mills, while magnetic fields are measured in teslas (T) or gauss (G) using ...
Electric vs Magnetic Field: Transferring Energy - Physics Forums
2010年6月18日 · However, a current distribution placed in a magnetic field will have some associated energy, [itex]W=\frac{1}{2}\int \textbf{H}\cdot\textbf{B} d^3x[/itex] (See section 5.16 of Jackson's Classical Electrodynamics 3rd ed. for a good brief discussion of energy in a magnetic field), since there are forces at play inside the distribution (usually ...
Electric Field vs Magnetic Field vs Electromagnetic waves - Physics …
2015年1月10日 · FAQ: Electric Field vs Magnetic Field vs Electromagnetic waves What is the difference between an electric field and a magnetic field? An electric field is a physical field that is created by electrically charged particles. It is a force field that can exert a force on other charged particles within its influence.
Comparison of Gravitational, Electric, and Magnetic Fields
2008年12月22日 · -Direction of field lines: toward center of charge Magnetic Fields:-Source: no point source, dipole required-Field intensity proportional to: n/a because no point source-Range: short range-Strength: strong-Direction of field lines: depends on the direction of the motion of a charge generating the magnetic field lines. otherwise they go from ...
Electron Properties: Electric vs Magnetic Fields - Physics Forums
2016年3月21日 · Electric and magnetic fields can interact with each other through a phenomenon known as electromagnetic induction. When a magnetic field changes, it can create an electric field, and vice versa. This is the principle behind generators and electric motors. What is the unit of measurement for electric and magnetic fields?
Electric Field vs Electromagnetic Field - Physics Forums
2013年1月10日 · FAQ: Electric Field vs Electromagnetic Field What is the difference between electric field and electromagnetic field? Electric field is a force field created by electrically charged particles, while electromagnetic field is a combination of electric and magnetic fields that are generated by moving charged particles.
Magnetic Induction vs. Field Strength - Physics Forums
2004年5月25日 · Magnetic induction is typically measured using a device called a magnetometer, which can detect the changes in a magnetic field caused by the presence of an external magnetic field. The unit of measurement for magnetic induction is the tesla (T) or the gauss (G). What factors affect magnetic induction and field strength? The strength of the ...
Relative Moving Charge: Electric vs Magnetic Field - Physics Forums
2008年6月29日 · As the velocity v increases, the strength of the magnetic field also increases. In summary, if you are moving at velocity v with respect to a single charge q, you will see both an electric field and a magnetic field. The strength of the magnetic field will depend on the velocity v and the charge q, and it will be stronger as the velocity increases.
Difference between Electric flux density,electric field strength
2011年2月20日 · I am clear with Electric field strength(=electric flux density) and electric flux. 1.)Does it mean that magnetic field strength=magnetic flux density? and... from what you said, magnetic field strength = magnetic field.But,here is what my book says: Magnetic field strength (H)=B/[tex]\mu[/tex] where B is magnetic flux density.
