A straight wire carries a current of 5A. Using the Right-Hand Grip Rule, how would you determine the magnetic field's direction if the current flows upward?
💡 Hint: What does your right hand look like when you follow this rule?
If the magnetic field at a distance of 0.1 m from a current-carrying wire is measured to be 1.5 T, calculate the magnetic field strength at a distance of 0.2 m.
💡 Hint: How does distance relate to the influence of the wire based on what we discussed in class?
