Step 1: Property of paramagnetic substances.
Paramagnetic substances are weakly attracted by a magnetic field and tend to move towards regions of stronger magnetic field. Step 2: Magnetic field between dissimilar poles.
Between two dissimilar magnetic poles, the magnetic field is strongest in the middle region. Step 3: Effect on the liquid.
Since the paramagnetic liquid is attracted towards the stronger magnetic field, it rises in the middle where the field strength is maximum. Step 4: Conclusion.
The liquid shows elevation in the middle.
