**Problem 5: A wire carrying current 10 mA experiences a force of 2 N in a uniform magnetic field. What is the force on it when current rises to 30 mA.**

**Solution**

When a current carrying wire is placed in a uniform magnetic field, it experiences a force F = BIL.

We do not know about B and L (Length of the wire). It is not possible to calculate them from the given data. However, the product BL can be calculated from the given data.

Put the values

Therefore,
