You are assigned the job of building a very sensitive magnetic scale. Objects are hung from a horizontal rod through which an electric current is directed from left to right. The rod is loosely attached to a pair of vertical rails that allow it to slide up and down with almost no resistance. The entire scale is placed in an external magnetic field, and the current is adjusted until the rod and object levitate, balancing the downward gravitational force with an upward magnetic force. B? 1. In which direction must the external magnetic field point in order for your scale to work? 2. What current is needed to balance the scale if the combined mass of the rod and object is 1 kg, the length of the wire is 1 meter, and the magnitude of the external magnetic field is O.1 Tesla?

Magnetic Field Of Coaxial Cable

The word coaxial means same axis. So for a long straight cable to be coaxial, it must have concentric cylindrical shaped conductor around it. Coaxial cable (popularly called ‘coax’) has various applications ranging from current conductors to radiofrequency signal transmitters. This cable has lower emission losses and provides protection from electromagnetic interference which allows signals with less power to transmit over longer distances.For example, currents produced in the pickup of a stereo turntable generally travel to the amplifier through a coaxial cable.The self-inductance of a coaxial cable is another important characteristic, because it influences the propagation of electrical signals in the cable.

Question

**Title: Building a Sensitive Magnetic Scale**

**Introduction:**
You are tasked with constructing a highly sensitive magnetic scale. Objects are suspended from a horizontal rod through which an electric current flows from left to right. This rod is loosely attached to vertical rails, allowing it to move up and down with minimal resistance. The scale operates in the presence of an external magnetic field, with the current calibrated such that the rod and attached object levitate. This balances the downward gravitational force with an upward magnetic force.

**Diagram Description:**
The diagram shows a horizontal rod, labeled with a current "I" flowing to the right. An object with mass "m" hangs from the rod. There is a question mark next to the letter "B," suggesting inquiry about the direction of the external magnetic field needed.

**Discussion Questions:**

1. **Direction of External Magnetic Field:**
In which direction must the external magnetic field point to ensure the function of the scale?

2. **Required Current for Balance:**
Calculate the necessary current to balance the scale given:
- Combined mass of the rod and object: 1 kg
- Length of the wire: 1 meter
- External magnetic field magnitude: 0.1 Tesla

**Conclusion:**
This activity explores the interplay of magnetic fields and electrical currents in creating forces capable of counteracting gravity.

You are lost in the woods! But you happen to have a magnetic field sensor with you. This sensor will tell you the direction of the Earth's magnetic field where you are. This is NOT a compass, but an actual device for measuring magnetic field. You know that you need to travel North (geographically) to reach the nearest town. Your sensor tells you that the magnetic field is pointing to your right. Which direction should you travel in order to go to the geographic North? Make sure to think about directions of magnetic field vs. the geographic directions. Question 8 options: To your Right Backward Forward To your Left
