Which of the following is not an artificial magnet?

Usually the North Pole of a magnetic needle is painted ______

Magnetic field induction of a uniform field is 0.385×10^–4 T and pole strength is 2Am Then find the force acting on magnet in C.G.S system?

To prevent demagnetisation the bar magnets are arranged in pairs with... poles facing each other

Magnetic keepers are used for ............... magnets

Lines of force runs from ___ to ___ inside the magnets

A magnet has pole strength 3Am and moment 24 Am2 Then find its length?

The smallest value of x² – 3x + 3 in the interval is

The alternate way to solve the question is to put both the values of interval of the function. Then we compare the values. We also check if the first derivative is postive or negative. If it's negative, the given function is decreasing. And if postive, the given function is increasing.
