JUMP-1069 10. A horizontal railroad track is placed in a magnetic field that is uniform from right to left. At one end of the track, the railroad wires are connected together to form a tram car, which is lying on the track. What will happen to the car when it turns on its own axis? Assume that effect from the magnetic field is negligible.
"a horizontal railroad track is placed in a magnetic field that is uniform from right to left. The as it first moves, but with time because the effect from the magnetic field is negligible, the car will stop moving.
### **`Why would a train stop moving in`** magnet field
Okay, I'm trying to understand why a train would stop moving in a magnetic field. The problem states that the railroad track is placed in a uniform magnetic field, and there's a tram car lying on the track. The car is made by connecting the railroad wires together. The question is about what happens to the car when it turns on its own axis.
At first, I'm a bit confused about the setup. The problem mentions that the railroad wires are connected together to form the tram car, but I'm not entirely sure how this works. Maybe the wires are part of the tram car's electrical system? The problem also states that the magnetic field is uniform, which means it's the same everywhere in the space.
### **`Understanding the Setup`**
Okay, I'll try to visualize the situation. There's a horizontal railroad track, and it's placed in a uniform magnetic field. The magnetic field is uniform from right to left. So, the magnetic field is constant in this direction.
The railroad wires are connected together to create the tram car. The car is lying on the track. So, the car is powered by these wires. Maybe the wires provide electricity to the car, which makes it move.
The question is about what happens to the car when it turns on its own axis. The problem also states that the effect from the magnetic field is negligible.
### **`Action of the Magnetic Field`**
Since the magnetic field is uniform, I think it doesn't cause any force on the car. If the magnetic field was uneven, it might cause a force, but since it's uniform, there's no force.
Wait, the problem states that effect from the magnetic field is negligible. So, the magnetic field isn't causing any significant effect on the car.
### **`Moving`**
The car is lying on the track. If it starts moving, it will move along the track. Since the magnetic field is negligible, I don't think the car will stop moving because of the magnetic field.
But the question is about what happens when the car turns on its own axis. I'm not sure what turning on its own axis means. Maybe it's rotating?
### **`Rotation`**
If the car is rotating, I'm not sure how the magnetic field would affect it. Since the magnetic field is negligible, maybe it won't cause any effect.
Wait, the problem states that the magnetic field is uniform from right to left. So, the magnetic field is pointing in this direction.
If the car is rotating, maybe it's moving through the magnetic field, creating a force. But since the effect is negligible, maybe this force won't stop the car.
### `Final Thoughts`
Since the effect from the magnetic field is negligible, I don't think the car will stop moving. The car will continue to move as it first moves, but with time, other factors like friction might cause it to stop.
### **`Answer`**
The car will continue to move as it first moves, but with time because the effect from the magnetic is negligible, the car will stop moving.
