Question
One alpha rays beam is incident along positive direction of + X-axis. It experiences a force along + Y-axis due to magnetic field. What is the direction of magnetic field?
✓

Answer

Since alpha are positively charged particles, so their direction will be direction of current. Hence by Fleming's left-hand rule, the direction of magnetic field will be along Z-axis.
