Unit for magnetic field.
A solenoid has a core made of material with relative permeability \(400\). The magnetic field produced in the interior of solenoid is \(1.0\,\text{T}\). The magnetic intensity in SI units is \(\alpha \times 10^5\). The value of \(\alpha\) is ________. \[ \text{Given: } \mu_0 = 4\pi \times 10^{-7}\,\text{SI units} \]
A voltmeter of resistance \( 300\,\Omega \) measures up to \( 150\,\text{V} \). Find the value of the shunt required to convert it into an ammeter capable of measuring \( 8\,\text{A} \).
What is the SI unit of magnetic flux?

Define Curie temperature in magnetism.

A paramagnetic material is kept in a magnetic field. The field is increased till the magnetization becomes constant. If the temperature is now decreased, the magnetization:
