Answer:
0.05 N
Step-by-step explanation:
Data provided in the question
The Wire carries a current of 4A to the left direction
The constant magnetic field of magnitude = 0.05 T
Pointing upward i.e Z direction
The wire is in the magnetic field = 25 cm
Based on the above information, the force on the current is
![= Current * constant\ magnetic\ field\ of\ magnitude * magnetic\ field](https://img.qammunity.org/2021/formulas/physics/college/6839zc92l0ziqlxje1dzord3xbg99m6fp9.png)
![= 4 * 0.05 * 0.25](https://img.qammunity.org/2021/formulas/physics/college/3z25scv9kfhx07vtwucpzslsc5nxybo5hh.png)
= 0.05 N
The direction will be the negative Y direction
