What detects the presence of a uniform magnetic field?

What detects the presence of a uniform magnetic field?

A simple compass can detect a magnetic field and demonstrate its direction. Iron filings can be used to show the shape of a magnetic field. At the sophisticated level, a gaussmeter can detect a field and indicate its strength, as measured in gauss units.

Can galvanometer determine the presence of magnetic field?

Tangent galvanometer. A tangent galvanometer is an early measuring instrument used for the measurement of electric current. It works by using a compass needle to compare a magnetic field generated by the unknown current to the magnetic field of the Earth.

Can magnetic needle determine the presence of magnetic field?

Only magnetic needle shows deflection in the presence in of magnetic field, therefore it can be used to determine the presence of magnetic field.

When the current is parallel to magnetic field?

Solution. If the current direction is parallel to the magnetic field, then there will no force on the conductor exerted by the magnetic field. Hence, the force experienced by current carrying conductor is \(0\).

How would you detect the presence of the magnetic field on an unknown planet?

A space traveller can detect the presence of magnetic field on an unknown planet by connecting the coil with the galvanometer and rotate the coil. if the galvanometer shows the deflection then magnetic field is present.

What instrument measures magnetic field?

gauss meter

How is magnetic flux measured?

Magnetic flux can be measured with a magnetometer. Suppose a probe of the magnetometer is moved around an area of 0.6 m2 near a large sheet of magnetic material and indicates a constant reading of 5 mT. Then the magnetic flux through that area is calculated as ( 5 ×10-3 T) ⋅ (0.6 m2 ) = 0.0030 Wb.

What is significance of BH curve?

The B-H curve is the curve characteristic of the magnetic properties of a material or element or alloy. It tells you how the material responds to an external magnetic field, and is a critical piece of information when designing magnetic circuits.
