`He^(2+)` ion travels at right angles to a magnetic field of `0.80 T` with a velocity of `10^5 m/s`. Find the magnitude of the magnetic force on the ion.

Explanation

To find the magnitude of the magnetic force on a `He^(2+)` ion traveling at right angles to a magnetic field, we can use the formula for magnetic force:

### Step-by-step Solution:

1. **Identify the given values**:
- Magnetic field strength, \( B = 0.80 \, T \) (Tesla)
- Velocity of the ion, \( v = 10^5 \, m/s \)
- Charge of the `He^(2+)` ion, \( q = 2 \times e \) where \( e \) (the elementary charge) is approximately \( 1.6 \times 10^{-19} \, C \).
