Time -to-live
A packet will not go around networks endlessly because it has a field in the header called the TTL field. This is a number that limits the number of hops or networks a packet will be forwarded to.
No
No, increasing the number of loops in a solenoid will actually increase the strength of its magnetic field. This is because more loops increase the amount of current flowing through the coil, which in turn increases the magnetic field produced.

Which two technologies can be used in distance vector routing protocols to prevent routing loops?
It is not necessary to avoid infinite loops. You are perhaps confusing infinite loops with endless loops which are to be avoided at all costs. An endless loop is an infinite loop that has no reachable exit condition; the loop will iterate until we forcibly terminate the program. We use the the term infinite loop in the sense that it is impossible to measure or calculate when the exit point will be hit. the following are all examples of infinite loops in their simplest form: for (;;) { // ... } while (true) { // ... } do while (true) { // ... } endless: // ... goto endless; The conditional expressions in each of these loops can never be false thus we cannot easily determine when these loops will exit. We typically use infinite loops when there are many exit conditions to consider and it is either impractical or inefficient to evaluate all of those conditions via the controlling expression alone. We take it as read the exit conditions are contained within the body of the loop. If the body of the loop has no reachable exit condition then it becomes an endless loop. It is the programmer's responsibility to ensure that all infinite loops can exit at some point.

STP (Spanning Tree Protocol) addresses the issue of network loops in Ethernet networks. Without STP, network loops can cause broadcast storms and packet collisions, leading to network congestion and performance degradation. STP helps prevent loops by identifying and blocking redundant paths in the network.
Routing Loops
Reducing the number of loops in the coil decreases the amount of current flowing through the electromagnet, leading to a weaker magnetic field strength. The strength of the magnetic field produced by an electromagnet is directly proportional to the number of turns of wire in the coil, so fewer loops result in a weaker overall magnetic field.

Magnetic field lines form closed loops, while electric field lines start and end on charges. Also, magnetic field lines do not begin or end; they always form continuous loops.
