Is a negative object attracting a neutral object considered magnetism?
"Negative" and "positive" are terms used with electrical forces, not with magnetic forces."Negative" and "positive" are terms used with electrical forces, not with magnetic forces."Negative" and "positive" are terms used with electrical forces, not with magnetic forces."Negative" and "positive" are terms used with electrical forces, not with magnetic forces.
Why ohm meter scale is reverse of other measuring devices?
For an analog ohmmeter, with a needle that moves left and right: The needle is spring loaded; when current is running through the meter, the current causes a small magnetic field in the windings of the meter mechanism, causing it do deflect to the right. If you're measuring current or voltage, if no current is running through the meter, then no deflection, so it should read zero on the left hand side of the scale. When measuring ohms (resistance) on an unenergized circuit, the battery in the meter provides the current. When you short the 2 leads together you have zero resistance to current (0 ohms). When you have an open circuit, no current flows, so there is an infinite resistance. So infinity is on the left side of the scale when no deflection, and zero is on the right side with maximum deflection (maximum current).
What is needed to determine the orientation of an orbital?
Magnetic quantum number (m_l) is needed to determine the orientation of an orbital.
How is magnets measured?
Magnetic reluctance is a concept used in the analysis of magnetic circuits. The term was coined in May 1888. There are several methods to determine the magnetic characteristics.
What of the following is evidence that an electrical current produces a magnetic?
You can detect the magnetic field by its pull on another magnet, including a compass needle.
What is an electrical current that produces a magnetic field?
The deflection of a magnetic compass in the presence of an electric current, is evidence that an electric current produces a magnetic field.
What is evidence that an electrical current produces a magnetic field?
The deflection of a magnetic compass in the presence of an electric current, is evidence that an electric current produces a magnetic field.
What is called the winding around the CRT yoke that deflects the electron beam with its magnetic field?
It's called a deflection coil. If a c.r.t. uses magnetic deflection, there will be two deflection coils, a horizontal one and a vertical one.
What are the applications of deflection magnetometer?
To compare the magnetic moments of two different bar magnets. To check the earth magetic moment. To verify inverse square law . Compare earth's magnetic induction . determine the horizontal component of the earth's magnetic induction .
How do you compare magnetic moments of two magnets using deflection magnetometer?
introduce it in magnetic field.

What is magnetic deflection senstivity?
Magnetic deflection sensitivity of a cathode ray oscilloscope (CRO) is defined as the amount of deflection of electron spot produced when a magnetic flux density of 1 Wb/m2 is applied. SM = (e / m )1\2 x 1\ (2V0) 1\2 x l x L
Light wave is composed of two components an electrical component and a component?
the answer is: magnetic...magnetic and electrical
Does a lodestone create a magnetic field?
A lodestone is magnetized and thus produces a magnetic field around it. This can be detected by the deflection of a compass needle.
Why deflection of the magnetic needle placed in a coil carrying current increases as the number of turns in the coil increases?
Deflection of the magnetic needle placed in a coil carrying current increases as the number of turns in the coil increase because as the number of turns in the coil increases the strength of the magnetic field also increases.
What checks should be done to an electrical measuring device before attempting to measure electrical resistance?
Some of the checks that can be done to an electrical device before checking electrical resistance include the proximity of other magnetic fields and other electrical circuits. Measure electrical resistance while at a safe distance from strong electrical circuits.
How are electrical circuits different from magnetic circuits?
What are the differences between electrical and magnetic circuit.
